Distribute so times what's outside by what's inside so 4×2x=8x and 4×7=28 then get x by itself by dividing on both sides 28÷8=3.5 your answer is x=3.5

Answer:
-42-20x
Step-by-step explanation:
Use PEMDAS, which is:
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
So first you would open parenthesis:
4x-42-24x
Then combine like terms:
4x-24x=-20x
Your answer would be -42-20x.

Answer:
2x²y⁴
Step-by-step explanation:
Area = W × L
W = A / L = 
= 2x²y⁴
Answer:
b = 9 ft
Step-by-step explanation:
Pythagorean Theorem:
a^2 + b ^2 = c^2
Given:
a = 12
b = ?
c = 15
Plug in values:
12^2 + b^2 = 12^2
Solve for b^2:
b^2 = 15^2 - 12^2
b^2 = 225 - 144
b^2 = 81
Take square root of both sides to find b:
sqrt(b^2) = sqrt(81)
b = 9
Hope this helps! :)
