the width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectang

yKpoI14uk [10]

Given:

The width of a rectangle is x centimeters and its length is (x+ 2) cm.

To find:

The expression for the perimeter of the rectangle.

Solution:

We know that, perimeter of a rectangle is

$Perimeter=2(Length+Width)$

We have,

Width = x cm

Length = (x+2) cm

Putting these values in the above formula, we get

$Perimeter=2((x+2)+x)$

$Perimeter=2(2x+2)$

$Perimeter=2(2x)+2(2)$

$Perimeter=4x+4$

Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.

pav-90 [236]

Answer: $y=-3x-2$

Step-by-step explanation:

Using the values $x=-2, y=4$ and $x=1, y=-5$ , the slope is $\frac{-5-4}{1-(-2)}=-3$ .

So, the equation is:

$y-4=-3(x+2)\\\\y-4=-3x-6\\\\y=-3x-2$

Greg have 24 more stickers than Wayne and Ronald have twice as much stickers than Wayne together they have 124 stick how much ea

lukranit [14]

G=24+w
r=2w
g+w+r=124
Substitute the values to get 24+w+w+2w=124
Simplifies to 4w=100. Therefore, Wayne has 25. Greg has 24 more than Wayne, so he has 49. Ronald would have 50.
