Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17
Answer: 394.6 m^3
Step-by-step explanation:
-
We are given expression:
.
Square root in exponent form is power
.
Therefore,
.
Now, replacing square root of 16 by
in original expression we are given, we get
.
Therefore,
<h3>

= 16 in simplest form. By the Power of Power rule,

. So,

must equal

in radical form.</h3>
