Find the lateral area and the total area of the prism.

Tems11 [23]

We have that

1) the lateral area----------------> L=P*h
P=(3+3+3) h=6
L=(3+3+3)*6=54 in²

the answer part 1) is the lateral area is 54 in²

2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2] P*h=54

S=2*[3*3/2]+54=63 in²

the answer part 2) is the total area is 63 in²

For each equation, find y when x=-3. Then find x when y = 2 1. y = 6x + 8

crimeas [40]

⬇ Hey, the answer is down below! :) ⬇

For y: x = -3

For y it stays the same.

For x: y = 2

For x it stays the same too.

For 1.): $x = \frac{1}{6}y + \frac{-4}{3}$

Step-by-step explanation:

For y there is no step-by-step explanation unfortunately.

For x there isn't a step-by-step explanation too unfortunately.

⬇ For 1.) there is a step-by-step explanation! ⬇

For step 1 we should flip the equations.

6x + 8 = y

For step 2 we should add -8 to both sides.

6x + 8 + − 8 = y + −8

= 6x = y − 8

For step 3 we should divide both sides by 6.

$\frac{6x}{6} = \frac{y - 8}{6}$

= x = $x = \frac{1}{6}y + \frac{-4}{3}$

In result we should have $x = \frac{1}{6}y + \frac{-4}{3}$ as the answer!
