5 is the answer to the promblem
Answer:
x = 6
Step-by-step explanation:
−16=−4(2x−8)
<u>Let's rearrange so solving would be easier.</u>
-4(2x-8) = -16
<u>Let's open the brackets. Please take note of the signs (+) (-).</u>
(-4 * 2x) + (-4 * -8) = -16
-8x + 32 = -16
<u>Subtract </u><u>32</u><u> from both sides. Please take note of the signs (+) (-).</u>
-8x + 32 (-32) = -16 (-32)
-8x + 0 = = -48
-8x = -48
<u>Divide both sides by </u><u>-8</u><u>.</u>
-8x/-8 = -48/-8
x = 6

Answer:
12x+4
Step-by-step explanation:
For the perimeter, we have to add up all sides of the triangle.
(3x-4) + (4x+5) + (5x+3)
3x-4+4x+5+5x+3
(3x+4x+5x) + (-4+5+3)
12x+4
