Answer:

14

Step-by-step explanation:

2 (x+4) = 3(x-2)

(distribute)

2*x + 2*4 = 3*x + 3 * -2

2x + 8 = 3x + -6

     +6          +6 (add 6 on both sides)

2x + 14 = 3x

-2x          -2x (subtract 2x on both sides)

14 = x

x is 14, we have found x.

What is 2(3x + 12y - 5 - 17x - 16y +4) simplified?
fiasKO [112]

Answer:

<h2>2(-14x-4y-1) / -28x-8y-2</h2>

Step-by-step explanation:

2(3x + 12y - 5 - 17x - 16y +4)

the 2 outside the bracket means we need to multiply everything by 2

=

6x+24y-10-34x-32y+8

now put all the like-terms together

6x-34x+24y-32y+8-10

now add them together

=-28x-8y-2

now find the HCF

2

put 2 outside the bracket and then divide every number by 2

2(-14x-4y-1)

this is as simplified it can get

The sides of the base of this square right prism are 16 centimeters each and the height of the prism is 10 centimeters. What is
Montano1993 [528]

The width (W) of the prism is 16 cm.

The length (L) of the prism is 16 cm.

The height (H) of the prism is 10 cm.

The formula for the surface area of any right prism with width W, length L, and height H is the following:

A = 2 (WL + LH + WH)

Substituting using our given values changes the equation to:

A = 2 (16*16 + 16*10 + 16*10)

= 2 (256 + 160 + 160) = 2 (576)

= 1152

Thus, the surface area is 1152 cm².

Let me know if you need any clarifications, thanks!
