Easy! If Smith had four daughters who each had 4 kids, then he had a total of 20 kids. I got this by multiplying the daughters by their kids, 4x4, and adding the four daughters, so it equals 20 kids in total!

Hope it helps!

The area of a rectangle is 14 yd2 , and the length of the rectangle is 3 yd less than twice the width. find the dimensions of th

ExtremeBDS [4]

Let x be the width
2x-3= length

(2x-3)(x)=14
2x^2-3x=14
2x^2-3x-14=0
(2x- 7)(x+2)=0
x=7/2 or x=-2

Since we know that negative values cannot exist in distance, we have to take 7/2 to as the correct answer.

The width would be 3.5 yards
Length= 2(3.5)-3
=4 yards

3.5 x 4 yards is the dimension of the rectangle

Hope I helped :)

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)
