Answer:

The answer is D.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

$3 {q}^{2} + {r}^{3} + 5r - 8q + 2( {q}^{2} + r)$

$= 3 {q}^{2} + {r}^{3} + 5r - 8q + 2 {q}^{2} + 2r$

Next you have to simplify by collecting like terms :

${r}^{3} + 3 {q}^{2} + 2 {q}^{2} + 5r + 2r - 8q$

$= {r}^{3} + 5 {q}^{2} - 8q + 7r$

The length of a rectangle is 3 meter shorter than3 times its width.Find the length and width if the perimeter is 210 meters

Shkiper50 [21]

Answer:

length = 78 m , width = 27 m

Step-by-step explanation:

let w represent width then length l = 3w - 3

the perimeter (P) is calculated as

P = 2l + 2w = 210 , substitute values

2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side

6w - 6 + 2w = 210

8w - 6 = 210 ( add 6 to both sides )

8w = 216 ( divide both sides by 8 )

w = 27 and l = 3(27) - 3 = 81 - 3 = 78

Then length = 78 m and width = 27 m
