Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean theorem, a^2 + b^2 = c^2.
a = 11
c = 20
11^2 + b^2 = 20^2
121 + b^2 = 400
b^2 = 279
b = sqrt(279) = 16.7

First multiply 40 and 10 to get 400. Then multiply 400 by 8 to get 3,200.
Your answer would be: 3,200
f(x) = 2|x + 6|-4
6=2|x + 6|-4
10= 2|x + 6|
divide by 2
5=|x + 6|
x = 5-6
x = -1
so x should be -1
