Answer:
x=1
Step-by-step explanation:
Its x=1 because if we put the 1 as in x then it will be like 2(1)+3(4(1)-3)= 8-3(1)
2(1)+3(4(1)-3) is equal to 5
8-3(1) is equal to 5
5=5
so x is 1
Answer:
A
Step-by-step explanation:
Step 1, setting variables:
We already know the <em>exact</em> height of the prism: 6 feet. We can set the unknown width as variable <em>x</em>, and length as <em>x+2 </em>(<u>length is two feet more than width</u>).
Step 2, writing equations:
Great! We have everything now. Let us write the equation by<u> substituting our variables in</u>:

Ok! Let us <u>expand</u> the equation:
