A rectangle's length is three times its breadth x metres. Write an expression
for the rectangle's:
a) perimeter
b) area

Answers

Answer:

1. Perimeter = 8x m

2. Area = 3x² m²

Step-by-step explanation:

From the question given above, the following data were obtained:

Breadth (B) = x m

Length (L) = 3B = 3x m

Perimeter (P) =?

Area(A) =?

1. Determination of the perimeter of the rectangle.

Breadth (B) = x m

Length (L) = 3x m

Perimeter (P) =?

P = 2(L + B)

P = 2(3x + x)

P = 2(4x)

P = 8x m

Thus, the perimeter of the rectangle is 8x m

2. Determination of the area of the rectangle.

Breadth (B) = x m

Length (L) = 3x m

Area(A) =?

A = L × B

A = 3x × x

A = 3x² m²

Thus, the area of the rectangle is 3x² m²

The length of a rectangle is one inch less than three times its width. If the perimeter of the rectangle is 118 inches, find the dimensions of the rectangle.

Answers

We can set up the width a X and, from the description the length would be 3X-1. The perimeter of a rectangle is determined by 2XL + 2Xw. Plugging into the equation 2(3X-1) + 2(X) = 118. Next distribute to get 6X-2 + 2X = 118. Combine like terms to get 8X = 120. Divide by 8 to get X = 15. The width is 15. The length is 3(15)-1 or 44. 88 +30 = 118

What are the steps for 2x+1=7

Answers

Answer:

x = 3

Step-by-step explanation:

Step 1:

Subtract 1 from both sides

2x + 1 = 7

2x + 1 - 1 = 7 - 1

2x = 6

(1 - 1 will cancel itself out on the side with the variable.)

Step 2:

Divide both sides by 2

2x = 6

2x ÷ 2 = 6 ÷ 2

x = 6 ÷ 2

(2 divide by 2, will cancel itself out on the side with the variable.)

Step 3:

Solve for x

6 ÷ 2 = 3

x = 6 ÷ 2 = 3

x = 3

What is the slope m and y-intercept of this image?

Answers

The slope (m) is 1. The y-intercept is 3.
You can use the formula m=y2-y1/x2-x1
When you plug the coordinates in, you get: 3-0/0-(-3)
This leaves you with 3/3, aka 1.
The y-intercept is whatever coordinate on the line makes contact with the y-axis. In this case, it is coordinate (0,3) making the y-intercept 3.
