Answer:

x = 25

Step-by-step explanation:

2x + 4 + x + 11 = 90, combine like terms

3x + 15 = 90, subtract 15 from both sides

3x = 75, divide by 3

x = 25, you have your answer!

Solve -9-8(1+4h)=-17

Mariulka [41]

-9-8(1+4h) = -17. We need to solve for h.
First, use the distributive property for 8(1+4h):
8(1+4h) = 8*1 + 8*4h = 8 + 32h

So -9-8(1+4h) = -17
-9 - (8+32h) = -17
-9 - 8 - 32h = -17
-17 - 32h = - 17
Add 17 on both sides to have the variables on a side and the numbers on the other:
-17 - 32h + 17 = -17 + 17
-32h = 0
divide both sides by -32 to get the variable h alone and its value on the other side:
(-32h)/-32 = 0/-32
h = 0.

So -9-8(1+4h) = -17 for h = 0.

You can recheck your answer (very important):
-9 - 8(1+4h) = -9 -8(1+4*0) = -9 - 8(1+0) = -9-8*1 = -9-8 = -17
The answer has been approved.

Hope this Helps! :)

PLEASE HELP<br> WILL GIVE BRAINLIEST FOR ANSWER AND EXPLANATION<br> I HAVE A TEST TOMORROW

krok68 [10]

I believe you just plug in the distance formula:
$25 = \sqrt{(y - 4) ^{2} + ( - 8 - 2) ^{2} }$
remove the radical by squaring both sides. then remove the exponents. you'll then have
$25 = (y - 4) + ( - 8 - 2)$
$25 = y - 4 - 10$
y equals 39. I'm not entirely sure about this. I hope I answered your question correctly
