Answer:

30.01 units

Step-by-step explanation:

Given vertices WXYZ:

W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)

Perimeter is the sum of the side length.

Use distance formula to find each side:

WX = $\sqrt{(2+4)^2+(4-5)^2} =\sqrt{37}$ ≈ 6.08
XY = $\sqrt{(3-2)^2+(-4-4)^2} =\sqrt{65}$ ≈ 8.06
YZ = $\sqrt{(-1-3)^2+(-6+4)^2} =\sqrt{20}$ ≈ 4.47
WZ = $\sqrt{(-1+4)^2+(-6-5)^2} =\sqrt{130}$ $\sqrt{(-1+4)^2+(-6-5)^2}=\sqrt{130}$ ≈ 11.40

Find perimeter:

P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units

Solve the absolute value equation. 4|4x - 3| - 8 = -4

soldier1979 [14.2K]

Answer:

x = $1,\frac{1}{2}$

Step-by-step explanation:

$4|4x-3|-8=-4\\$

Add 8 to both sides;

4|4x - 3| = 4 4|4x - 3| = -4

Divide both sides by 4;

4x - 3 = 1 4x - 3 = -1

Add 3 to both sides;

4x = 4 4x = 2

Divide both sides by 4;

x = 1 x = $\frac{1}{2}$

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.

jarptica [38.1K]

Formula for perimeter of rectangle:
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft

Answer: 252 ft
