Hello there!
Answer:
[tex]36 - 25x^{2}y^{2}[/tex]
Step-by-step explanation:
We can use the special formula:
[tex](a - b)(a + b) = a^{2} - b^{2}[/tex]
If a = 6 and b = 5xy then:
[tex](6 - 5xy)(6 + 5xy) = 6^{2} - (5xy)^{2} = 36 - 25x^{2}y^{2}[/tex]
This is the final answer
But if we don't know this formula, we can solve it other way:
[tex](6 - 5xy)(6 + 5xy) = 6^{2} + 5xy * 6 - 5xy * 6 - (5xy)^{2} = \\\\= 6^{2} - (5xy)^{2} = 36 - 25x^{2}y^{2}[/tex]
Sophia was going out to eat with some of her friends. The bill for the food
was $62. They wanted to leave a 20% tip. What was the total that Sophia
and her friends paid? Explain how you found your answer.
Answer:
$12.40
Step-by-step explanation:

If 5 inches is added to both the length and the width of a rectangle, then the
perimeter is increased by -
Answer
the perimeter is increased by 5
Step-by-step explanation:
If 5 inches is added to both sides of the rectangle. Then the perimeter of the rectangle is increased by 20.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
If 5 inches is added to both the length and the width of a rectangle.
Then the new perimeter of the rectangle is given as,
P = 2[(L + 5) + (W + 5)]
P = 2[L + W + 10]
P = 2(L + W) + 20
If 5 inches is added to both sides of the rectangle. Then the perimeter of the rectangle is increased by 20.

gym?
Answer:
72m
Step-by-step explanation:
Given data
Area= 2,952 m^2
Width=41m
We know that
Area= Length*width
Substitute
2,952= Length*41
Length= 2,952/41
Length= 72m

Making connections between arithmetic sequences and linear function
Use the graph or the formula to write the equation of the line in a slope intercept form
Arithmetic sequences are those in which the difference between each subsequent phrase is a fixed number. This is shown by writing the equation for a line as y = mx+c, where m denotes the slope and c the y-intercept.
What is the relationship between arithmetic sequences and linear functions?The origin is the place where the X and Y axes always meet. Point (0, 0) on the XY plane is where the origin is situated. The XY plane is divided into four distinct quadrants using symmetry and the origin.Our origin will not be in the specified place if we added negatives to the axes as in the example presented. This indicates that the XY plane's four quadrants are not properly separated.This means that, as seen in the provided illustration, we are unable to include negatives on the axes. It primarily involves incorrect notation. A linear function is an algebraic sequence. Where d represents the common difference and c is a constant, we write an=dn+c in place of y=mx+b.To learn more about arithmetic sequences refer to :

7. The rectangle below is dilated by a scale factor of
3.6
to create a new rectangle. Which of the following
could be the dimensions of the new rectangle?
The new dimension of the rectangle is 14.4 cm ×5.4 cm option (A) is correct if the rectangle is dilated by a scale factor of 3.6.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a rectangle shown in the picture.
The width of the rectangle = 1 1/2 = 3/2 = 1.5 cm
The length of the rectangle = 4 cm
The rectangle is dilated by a scale factor of 3.6:
The new width of the rectangle = 1.5×3.6 = 5.4 cm
The new length of the rectangle = 4×3.6 = 14.4 cm
The dimension of the new rectangle = 14.4 cm ×5.4 cm
Thus, the new dimension of the rectangle is 14.4 cm ×5.4 cm option (A) is correct if the rectangle is dilated by a scale factor of 3.6.

Ayesha earns a 10 percent bonus based on her annual salary plus the number of sales shes earned and a 2,000 dollar bonus last year
The annual salary will be 49750
Gross salary would be the total amount of compensation that an employer or business pays an employee during their employment. The Cost of Company, as well as CTC, on the other hand, would represent the overall compensation of employees. The CTC seems to be an employee's gross pay, but their net compensation is how much they actually take home.
Now, According to the question:
Let x be the annual salary.
Then 10% of x+250 equates 0.1(x+250).
Thus, the bonus equates $5000, then we will get the equation:
0.1(250 + x) = 5000
Solving for 'x' we get:
250 + x = [tex]\frac{5000}{0.1}[/tex]
250 + x = 50000
x = 50000 - 250
x = 49750
CTC and gross salary are sometimes confused. But there is a distinction among the two. Before taxes, Employee Provident Fund (EPF) contributions, and gratuities deducted from the CTC, the amount paid to the employee would be known as their gross salary.
The complete question is this:

write the equation of the line in fully simplified slope intercept form
The equation of a line can be written in both slope-intercept form and standard form.
Write the equation of the line in fully simplified slope intercept form?The equation of a line in slope intercept form is written as y = mx + b, where m is the slope of the line, and b is the y-intercept of the line.The simplified form of the equation of a line is obtained by first identifying the slope of the line. The slope of a line is the ratio of the vertical change (rise) over the horizontal change (run). The slope of a line is written as m = (y2 - y1)/(x2 - x1).Next, the y-intercept of the line is found. The y-intercept is the point where the line intersects the y-axis. To find the y-intercept, substitute the slope into the equation of the line and solve for b.Once the slope and y-intercept have been determined, the equation of the line can be written in fully simplified slope intercept form as y = mx + b.For example, if the slope of a line is 4 and the y-intercept is 6, then the equation of the line in slope intercept form is y = 4x + 6.To learn more about slope intercept form refer to:
