Answer:
144 cubic inches
Step-by-step explanation:
a=lxwxh a=6*6*4
It is close to 200 because 150 or above would be rounded to 200. Below 150 would be 100
|4-24x|=52
24x=56
2.333~ is your answer
6x^2 + 4(x^2 - 1) =
6x^2 + 4x^2 - 4 =
10x^2 - 4 <===
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
