Alisiya [41]

Answer:

(5.5, 12.5) OR (11/2, 25/2)

I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.

Step-by-step explanation:

We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.

Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)

(x1 + x2 / 2, y1 + y2 / 2)

(<u>-4 + 15</u> / 2, <u>22 + 3</u> / 2)

(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

Hope I answered your question. Stay safe, happy, and healthy, thank you :) !!

A rectangle’s width is 2 meters shorter than its length, l. Its area is 168 square meters. Which equation can be used to find th
bija089 [108]

Answer:

l(l - 2) = 168

Step-by-step explanation:

Let w = width

Let l = length

Let A = area

w = l - 2

A =  l * w

also, A = 168

equating the two values of A

l * w = 168

l * (l - 2) = 168

l^2 - 2l = 168

l(l - 2) = 168
