Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= ![\[2* [(5 + 2y) + (10 + 4y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%285%20%2B%202y%29%20%2B%20%2810%20%2B%204y%29%5D%5C%5D)
Simplifying,
= ![\[2* [(15+6y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%2815%2B6y%29%5D%5C%5D)
= ![\[(30+12y)\]](https://tex.z-dn.net/?f=%5C%5B%2830%2B12y%29%5C%5D)
Hence the perimeter of the rectangle is given by (30 + 12y)
Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
Answer:

Answer: 2n+4
Step-by-step explanation:
"(4 more than) <u>twice the number</u>" is 2x
"<u>4 more</u> (than twice the number)" is +4
Put them together: 2n + 4
