What is the distance betweem points W and X to the nearest hundredth?

Arte-miy333 [17]

Answer:

16.97 Units

Step-by-step explanation:

From the graph

Point W is located at (-6,4)

Point X is located at (6,-8)

To determine the distance between points W and X, we use the distance formula.

$\text{Distance Formula}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$(x_1,y_1)=(-6,4)\\(x_2,y_2)=(6,-8)$

So,

$WX=\sqrt{(6-(-6))^2+(-8-4)^2} \\=\sqrt{(6+6)^2+(-12)^2}\\=\sqrt{(12)^2+(-12)^2}\\=\sqrt{288}\\=16.97$ units (correct to the nearest hundredth)$

Set up an equation and solve. the width of a rectangle is 3 more than twice its length. the perimeter is 60 feet. find the width

a_sh-v [17]

Length (L): 2w + 3

width (w): w

Perimeter (P) = 2L + 2w

60 = 2(2w + 3) + 2(w)

60 = 4w + 6 + 2w

60 = 6w + 6

54 = 6w

9 = w

Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21

Answer: width = 9 feet, length = 21 feet
