So you do 2L+2W=36
2×10+2W=36
36-20=16
16÷2=8
So the width is 8

(6m^3 -16m^2 + 15m - 40) / (2m^2 + 5)

Helen [10]

6m3 - 16m2 + 15m - 40 Simplify ————————————————————— 2m2 + 5 Checking for a perfect cube :

4.1 6m3 - 16m2 + 15m - 40 is not a perfect cube

Trying to factor by pulling out :

4.2 Factoring: 6m3 - 16m2 + 15m - 40

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 15m - 40
Group 2: -16m2 + 6m3

Pull out from each group separately :

Group 1: (3m - 8) • (5)
Group 2: (3m - 8) • (2m2)
 -------------------
Add up the two groups :
 (3m - 8) • (2m2 + 5)
Which is the desired factorization

3m-8 is the answer

The perimeter of a rectangle is 72 cm. The length is 3 more than twice the width What

solmaris [256]

<h3>Solution</h3>

Given :-

Perimeter of rectangle = 72 cm
The length is 3 more than twice the width.

Find :-

Dimensions of rectangle

<h3 /><h3>Explantion</h3>

Using Formula

$\boxed{\underline{\tt{\red{\:(perimeter_{rectang}\:=\:2\times (Length+Width)}}}}$

Let,

Length of Rectangle = x cm
Breadth of Rectangle = y cm

According to question,

==> perimeter of Rectangle = 72

==> 2(x+y) = 72

==> x + y = 72/2

==> x + y = 36_________________(1)

Again,

==> x = 2y + 3

==> x - 2y = 3__________________(2)

Subtract equ(1) & equ(2)

==> y + 2y = 36 - 3

==> 3y = 33

==> y = 33/3

==> y = 11

keep in equ(1)

==> x - 2×11 = 3

==> x = 3 + 22

==> x = 25

<h3>Hence</h3>

Length of Rectangle = 25 cm
Width of Rectangle = 11 cm
