Answer:

\frac{7}{x+7}

Step-by-step explanation:

<u>Step 1:  Pull a 7 from the top</u>

<u />\frac{7x + 42}{x^2 + 13x + 42}

\frac{7(x + 6)}{x^2 + 13x + 42}

<u>Step 2:  Factor the bottom</u>

<u />\frac{7(x + 6)}{(x + 7)(x + 6)}

<u>Step 3:  Cancel the top (x+6) and the bottom (x+6)</u>

<u />\frac{7}{x+7}

Answer:  \frac{7}{x+7}

Hailey is knitting a scarf. Each half hour, she adds 3/7 inch to the scarf's length. How much length will she add to the scarf i
BARSIC [14]
Take 3/7 and multiply it by 2 to find out how much she knits in one hour. Then take that value and multiply by 12 to find out how much she knits in 12 hours.

3/7 x 2 = 6/7
6/7 x 12 = 72/7 or 10 2/7.

Help please been stuck on this for a week.

They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder.  Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =
</span></span>
<span> <span> <span> 452.39 cubic inches which is the lateral area.</span></span></span>

Complete the statement by typing the letter of the angle.<br> m∠ =54º
tekilochka [14]

Answer:

x = 16

∠A = 39

∠B = 54

∠C = 87

Step-by-step explanation:

Make a equation of all of the angles added together is equal to 180 since the angles of a triangle added together is 180

(4x-10)+(2x+7)+(7x-25)=180

combine like terms

4x+2x+7x-10+7-25 = 180

13x-28=180

solve for x

13x=208

x = 16

plug in x to find the measure of the angle

∠A = 2(16) + 7 = 39

∠B = 4(16) - 10 = 54

∠C = 7(16) - 25 = 87

Add them together to double check your answer

39 + 54 + 87 = 180

hope this helps
