Answer:
Multiply using the distributive property.
6 x + 30
Step-by-step explanation:
reverse 6x+30=6(x+5)
Factor 6 out of
6 x + 30 =6 ( x + 5)
X^2 +6x+30 in vertex form
Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29

4 x + 6 < − 6...............................................................
Answer:
x < - 3
Step-by-step explanation:
Given
4x + 6 < - 6 ( subtract 6 from both sides )
4x < - 12 ( divide both sides by 4 )
x < - 3

Thomas wants to put a fence around a rectangular garden that is 12 feet long and 7 feet wide.
How much fencing he will need?
Answer:
84 feet
Step-by-step explanation:
he will need 84 ft to cover the entire garden
Answer:
38 ft of fencing
Step-by-step explanation:
The perimeter of a rectangle is 2L + 2W, where L and W are the length and width, respectively. The dimensions of the garden are given, 7 x 12 ft.
The amount of fencing needed is 2(7) + 2(12) = 14 + 24 = 38 ft of fencing

y=7x−7z−9
Answer:
[tex]x=\frac{y+7z+9}{7}[/tex]
Step-by-step explanation:
[tex]7x-7z-9=y[/tex]
[tex]7x-7z-9+7z=y+7z[/tex]
[tex]7x-9=y+7z[/tex]
[tex]7x-9+9=y+7z+9[/tex]
[tex]7x=y+7z+9[/tex]
[tex]\frac{7x}{7}=\frac{y}{7}+\frac{7z}{7}+\frac{9}{7}[/tex]

PART A:
A car traveled 180 miles at a constant rate.
complete the table to show the rate at which the car was traveling if it was completed the same distance in each number of hours
travel time | rate of travel
5
4.5
3
2.25
PART B:
In the scenario in part a write an equation that would make it easy to find the rate at which the car was traveling in miles per hour r, if it traveled t hours
Answer:
Part B: r = 180/t
Step-by-step explanation:
Find the coeficcient of the x4y3 term in the expansion of (2x+y)7
By the binomial theorem,
[tex]\displaystyle (2x+y)^7 = \sum_{k=0}^7 \binom7k (2x)^{7-k} y^k=\sum_{k=0}^7 \binom7k 2^{7-k} x^{7-k} y^k[/tex]
where
[tex]\dbinom nk=\dfrac{n!}{k!(n-k)!}[/tex]
is the binomial coefficient.
We get the x⁴y³ terms with k = 3, for which the coefficient would be
[tex]\dbinom73 2^{7-3}=\dfrac{7!}{3! 4!} 2^4=\boxed{560}[/tex]
In triangle ABC, the measure of angle B is 50 degrees. Select all possible values for the measures of A and C if ABC is an acute triangle. m\angle∠A= 58 degrees; m\angle∠C= 72 degrees m\angle∠A= 100 degrees; m\angle∠C= 30 degrees m\angle∠A= 80 degrees; m\angle∠C= 50 degrees m\angle∠A= 60 degrees; m\angle∠C= 70 degrees m\angle∠A= 90 degrees; m\angle∠C= 40 degrees m\angle∠A= 105 degrees; m\angle∠C= 25 degrees
Answer:
Step-by-step explanation:
Sum of angle in a triangle = 180°
<A+<B+<C = 180
Given <B = 50°
Substituting into the formula
<A+50+<C = 180
<A+<C = 180-50
<A+<C = 130°
Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°
The possible values of <A and <C that will be acute and give a sum of 130° are;
∠A= 58° and ∠C= 72°
∠A= 80° and ∠C= 50°
∠A= 60° and ∠C= 70°
You can see that all the Angles are less than 90° and their sum is 130°
X=y than y=x what’s the property of equality
Answer:
Symmetric Property
Step-by-step explanation:
Symmetric Property, because it tells that the both sides of the equal sign are actually equal, regardless of which side of the equal sign.
If [tex]x = y[/tex], then [tex]y = x[/tex].
