Mathematics
1 answer:
lara [203]3 years ago

The dimensions of a rectangle are -3x - 2 and 10x - 9 The simplified expression for the rectangle's perimeter is 14x – 22

<u>Solution:</u>

Given that dimensions of a rectangle are -3x – 2 and 10x – 9

Let’s say width of the rectangle = w = -3x – 2

And length of the rectangle = l = 10x – 9

<em><u>The formula for perimeter of rectangle is given as:</u></em>

Perimeter of rectangle = 2 (l + w)  

By substituting the length and width values we get,

=> Perimeter of rectangle = 2 [(10x – 9  ) + ( -3x – 2 )]

On simplification we get,

= 2 (10x – 9 – 3x – 2 )  = 2 (7x – 11)  

=> Perimeter of rectangle = 14x – 22

Hence simplified expression for the rectangle's perimeter having dimensions as -3x - 2 and 10x – 9 is 14x – 22

For which points in the same quadrant as(2,-10)could Tamara use a number line to find the distance?
VLD [36.1K]

ANSWER

(2,-2)

(10,-10)

(2,-9)

(7,-10)

EXPLANATION

The given point is (2,-10)

This point is in the fourth quadrant.

To be able to use the number line to find the distance between this point , (2,-10) and another point in the fourth quadrant, the second point must have the same x-coordinate with this point or the same y-coordinate with this point.

These points are:

(2,-2)

(10,-10)

(2,-9)

Suppose that the perimeter a rectangle is 54 feet, and the length is 13 feet more than the width. Find the width ractangle, in f
Vesnalui [34]

Answer:7feet

Step-by-step explanation:

perimeter(p)=54ft

Width(w) +13=Length(L)

Perimeter=2xLength+2xwidth

P=2xL+2xw

L=w+13

54=2(w+13)+2w

54=2w+26+2w

Collect like terms

54-26=2w+2w

28=4w

Divide both sides by 4

28/4=4w/4

7=w

Width =7feet
