The perimeter of a rectangle is P= 2L +2W, where L is the length and W is the width. If the perimeter is 200 feet and the length

Katena32 [7]

Answer:

Length - 70

Width - 30

Step-by-step explanation:

Let the width be x

Length is 40 more than width which makes length = x + 40

Perimeter = 2L + 2W

2(x + 40) + 2(x)

Open brackets

2x + 80 + 2x = 4x + 80

Perimeter = 200

200 = 4x + 80

4x = 200 - 80

4x = 120

x = 120/4

x = 30

Width = 30

Length = x + 40 = 70

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-5, 0)

Point (-9, -8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-8-0}{-9+5}$
[Fraction] Subtract/Add: $\displaystyle m=\frac{-8}{-4}$
[Fraction] Divide: $\displaystyle m=2$

Find x, y and z for the following triangle. Please show the steps with details, Thanks!

Lubov Fominskaja [6]

Answer:

x = 100°

y = 125°

z = 55°

Step-by-step explanation:

A straight line is 180°

A triangle is 180°

Solve in this order:

X: 180 - 80 = 100

Z: 180 - 80 - 45 = 55

Y: 180 - 55 = 125

69+5.75= 74.75

74.75+5.75=80.5

80.5+5.75= 86.25

86.25+5.75=92

basically this formula should help
