Answer: the value of y is 1. If needed, the value of x is 4.
Step-by-step explanation:
See paper attached. (: I went ahead and solved for x too, just in case.
Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A =
and l =
, thus
V =
×
( cancel 21 and 3 by 3 and 2 and 8 by 2 )
=
×
= 7 × 4 = 28 units³
Solve the equation:
– 3b – (– 2) = 4b <span>– 12
</span>– 3b + 2 = 4b – 12
– 3b = 4b – 12 – 2
– 3b = 4b – 14
– 3b – 4b = – 14
– 7b = – 14
– 14
b = ———
– 7
b = 2 <——— solution.
I hope this helps. =)
