Remember to do the same thing to both sides

use distributive prpoerty which is
a(b+c)=ab+ac so
pemdas
multiplication
8(x+1/4)=8x+8/4=8x+2
3(6x-9)=18x-27

now we have7x+8x+2=18x-27-8
add like terms
15x+2=18x-35
subtract 15x from both sides
2=3x-35
add 35 to both sides
37=3x
divide both sides by 3
37/3=x
12 and 1/3=x

HELP FAST PLEASE!!<br> FIND THE SURFACE AREO OF EACH RECTANGULAR PRISM
tatyana61 [14]

The surface area of the rectangular prism is 3668.94 m²

<h3>Calculating Surface area </h3>

From the question, we are to determine the surface area of the rectangular prism

Surface area of a rectangular prism is given by the formula,

Surface area = 2(lw + lh + wh)

Where l is the length

w is the width

and h is the height

From the given diagram,

l = 35.7 m

w = 25.5 m

h = 15.1 m

Putting the parameters into the formula, we get

Surface area = 2(35.7×25.5 + 35.7×15.1 + 25.5×15.1)

Surface area = 2(910.35 + 539.07 + 385.05)

Surface area = 2(1834.47)

Surface area = 3668.94 m²

Hence, the surface area of the rectangular prism is 3668.94 m²

X^2 - 4x + 2x – 8 = 2(x + 2)
zhenek [66]

Answer:

x = 6 or x = -2

Step-by-step explanation:

x^{2}  - 4x + 2x - 8 = 2(x + 2)\\x^{2}  - 4x + 2x - 8 = 2x + 4\\x^{2}  - 4x - 12 = 0\\(x-6)(x+2) = 0\\
