D. 1/4 + 1/5 = 5/20 + 4/20 = 9/20 = 45/100 = 0.45
First, try 99^3 = 970299; therefore, it is not the least possible value.
The above number is a multiple of 99, so we can factor this out to find the least possible value. So we try to factor 99:
99 = 9 * 11
99 = 3^2 * 11^ 1
and 3^3 * 11^3 = 35937
The least possible value is 4^1 + 11^2 = 125. Its sum is 125 which is a perfect cube.
<span>You are given a rectangular picture measuring 8 inches by 7 inches. Also, Alistair wants this to be framed and that the total area is 34 square inches. The width of the frame is x inches. To solve the dimension of the frame with value of x we have:
We have to assume that x here will be equal to all sides of the frame and so, using the area of the rectangle, we can model the equation like this:
A = LW (where A is the area, L is the length and W is the width)
36 = (8 - x)(7 - x)
36 = 56 - 8x - 7x + x</span>²
<span>x</span>² - 15x +20 = 0 → model of our equation and in quadratic form
x² - 15x + 20 = 0
using a calculator, x = 1.48 inches

3.Use the equation you created in part A to find the width of the picture frame</span>
