Answer:

Step-by-step explanation:

plug in 3 where the xs are

2(3)(6(3)-5(3))+(3)^2(5(3)-4(3)=45

2(3)=6

6(3)=18

-5(3)=15

(3)^2=9

5(3)=15

-4(3)=-12

Z + 6 over 3 = 2z over 4

Black_prince [1.1K]

$\frac{z + 6}{3}$ = $\frac{2z}{4}$ Multiply both sides by 3
z + 6 = $\frac{(3)2z}{4}$ Multiply both sides by 4
(4)z + 6 = (3)2z Simplify
4z + 24 = 6z Subtract 4z from both sides
24 = 2z Divide both sides by 2
12 = z Flip the sides to make it easier to read
z = 12

A right rectangle prism has a length of 5 cm a width of 4 cm and a height of 3 cm the dimensions of the prism are doubled what i

IRISSAK [1]

Answer: 376 cm^2

Step-by-step explanation:

First you would double all the dimensions:

l = 5 cm x 2 = 10 cm

w = 4 cm x 2 = 8 cm

h = 3 cm x 2 = 6 cm

The formula for finding the surface area of a rectangular prism is A=2(wl+hl+hw)

Substitute the values:

A=2(8*10+6*10+6*8)

Solve using PEMDAS:

A=2(80+60+48)

A=2(188)

A=376

Surface area is always in units^2:

376 cm^2
