Answer:

56 minutes

Step-by-step explanation:

14 people painting 14 walls is simply <em>double</em> (x2) 7 people painting seven walls.

We know this because 7 x 2 = 14

So, we will have to double the amount of time it takes them to paint.

28 x 2 = 56

It will take 56 minutes for 14 people to paint 7 walls!

the length of a rectangle is 8 feet more its width.the area of the rectangle is 84 square feet find its length and width
S_A_V [24]

Answer:

length=8+w........1

area=84square feet........2

area of rectangle =length x width

area=(8+w)x W

area=8w+w^2

84=8w+w^2

w^2+8w+(4^2)=84+(4^2)

(w+4)^2=84+16

(w+4)^2=100

√(w+4)^2=√100

w+4=±100

w+4=100 or w+4=-100

w=96 or w=-104

the answer is <u>9</u><u>6</u>
