The product of expression is 24a² - 18ab.
What is Polynomial?A polynomial is a sort of algebraic expression in which all variable exponents are whole numbers. Variable exponents in any polynomial must be non-negative integers. A polynomial is made up of constants and variables, however we cannot divide polynomials by variables.
We have,
3a( 8a - 6b)
Now, multiplying the expression as
= 3a(8a) - 3a(6b)
= 24a² - 18ab

Answer:
y = 3/2x - 3
Step-by-step explanation:
first find slope (m):
m = (-3/2 -(-15/2)) / (1 - (-3)) = (12/2) / 4 = 6/4 = 3/2
plug the point (1, -3/2) into the point-slope form (y-y1) = m(x-x1):
y - (-3/2) = 3/2(x-1)
y + 3/2 = 3/2x -3/2
now put it in slope-intercept form y = mx + b:
y = 3/2x -6/2
y = 3/2x - 3
Rich added 26.2 milliliters of water to a solution in science class. The directions said to add 22.6 milliliters of water. What was the percent error (to the nearest hundredth percent) in the amount of water Rich added
The percent error in the amount of water Rich added is 15.93%.
What is meant by percentage error?When compared to the actual value, the percent error is the difference between the estimated and actual values.
The difference between the estimated value and the actual value in relation to the actual value is given as a percentage and is known as the percent error. In other words, the relative error times 100 equals the percent error.
Given that Rich added water to a solution in science class is 26.2 milliliters
Whereas the directions said to add water is 22.6 milliliters
The amount of water that is added more is 26.2 -22.6 = 3.6 milliliters
The percent error is = (3.6/22.6)*100%
The percent error is = 15.9292*100%
Therefore, the correct answer is option b) 15.93%.

The equation of the line in slope-intercept form, with the point (4, -5) and an undefined rate of change is x = 4.
What is the slope-intercept form?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope or rate of change.x and y represents the data points.c represents the y-intercept.In Mathematics, any line that has an undefined slope (rate of change) is a vertical line because it does not have a y-intercept. This ultimately implies that, a vertical line that is parallel to the y-coordinate (y-axis) would have an undefined slope (rate of change).
Generally speaking, the equation of a line that has an undefined slope (rate of change) is given by this mathematical expression;
x = a
Where:
a represents the x-intercept.
At point (4, -5), the required equation with an undefined slope (rate of change) is x = 4.

The interior angles of the triangle are [tex]70^{\circ}, (14+6x)^{\circ}[/tex], and [tex](3x-3)^{\circ}[/tex].
Angles in a triangle add to [tex]180^{\circ}[/tex].
[tex]70+14+6x+3x-3=180 \\ \\ 81+9x=180 \\ \\ 9x=99 \\ \\ x=11[/tex]

8^x/2 divided by 4^x/3 equals 2^-5/2
The solution to the exponential equation 8^(x/2)/4^(x/3) = 2^(-5/2) is given as follows:
x = -6/5.
How to solve the exponential equation?The exponential equation for this problem is defined as follows:
[tex]\frac{8^{\frac{x}{2}}}{4^{\frac{x}{3}}} = 2^{-\frac{5}{2}}[/tex]
Both 8 and 4 are powers of 2, as follows:
8 = 2³.4 = 2².Applying the power of power rule (multiplying the exponents), the expression on the left side can be rewritten as follows:
[tex]\frac{2^{\frac{3x}{2}}}{2^{\frac{2x}{3}}} = 2^{-\frac{5}{2}}[/tex]
When two terms with the same base and different exponents are divided, we keep the base and subtract the exponents, hence:
[tex]\frac{2^{\frac{3x}{2}}}{2^{\frac{2x}{3}}} = 2^{\frac{3x}{2} - \frac{2x}{3}}[/tex]
The subtraction is obtained as follows:
3x/2 - 2x/3 = 9x/6 - 4x/6 = 5x/6.
(as the least common factor of 2 and 3 is of 6).
Then the simplified expression is of:
[tex]2^{\frac{5x}{6}} = 2^{-\frac{5}{2}}[/tex]
As the exponential function y = 2^x is injective, the solution is obtained as follows:
5x/6 = -5/2.
10x = -12
x = -6/5.

Show how to use inverse operations to check your answer.
Answer:
1) 12.2425 square meters
2)$288
Step-by-step explanation:
According to the problem, we have a rectangle bedroom with 415cm long by 295cm width.
We know that 1cm = 0.01 m
Length of bedroom: 415 x 0.01 = 4.15m
of bedroom: 295 x 0.01 = 2.95m
area of rectangle: Length x Width
Area: 4.15 x 2.95 = 12.2425 square meters
We have a cost of carpet 24 per square meter is given from the problem.
we now know that it is in a whole number so we divide by 2 to get it square
A= 12m (squared)
now we multiply 12 and 24
we get $288

What are supplementary angles?Angles are formed whenever two or more straight lines intersect. These angles produced thus have individual and some common properties of which some can add up to form complementary angles, or supplementary angles.
Two angles are said to be supplementary if the value of their sum add up to 180^o.
From the given question, we can deduce that;
m<1 + m<2 = 180^o (definition of complementary angles)
(17x - 30) + (7x + 18) = 180^o
17x - 30 + 7x + 18 = 180^o
24x - 12 = 180
24x = 180 + 12
24x = 192
x = 192/ 24
= 8
x = 8

Mrs. Smith calls customer care after she receives her phone bill. Her bill is normally $40. 00 per
month, however, this month it is $110. 0. Mrs. Smith negotiates a 50% credit of the difference
between the normal charge of $40. 00 and the current balance of $110. 0. How much will Mrs.
Smith be responsible for paying?
Mrs. Smith will be responsible for paying $75.00
The normal monthly charge is $40.00 and the current balance is $110.00,
so the difference is $110.00 - $40.00 = $70.00.
Mrs. Smith negotiated a 50% credit, so she will receive
$70.00 x 0.50 = $35.00 credit.
To find the amount she is responsible for paying, we subtract the credit from the current balance
$110.00 - $35.00 = $75.00
Thus, the amount Mrs. Smith will be responsible for paying is $75.00
