Answer:

68 inches^2

Step-by-step explanation:

The shape is a rhombus

A rhombus is a four sides quadrilateral with the four sides equal in length

The area of a rhombus = $\frac{1}{2}pq$

where p and q are the two diagonals

1/2 x (8 x 17) = 68 in²

Lily bought 22.17 pounds of grapefruit. The lightest grapefruit weighed 1.3 pounds. The heaviest grapefruit weighed 1.7 pounds.

Approximately 15 grapefruits

Step-by-step explanation:

Average Value

The mean or average of a sample is a number that represents the whole set by the center value of them. The formula to compute the average is

$\displaystyle \bar x=\frac{\sum x_i}{n}$

Where xi is the value of the element i and n is the number of elements in the set

We need to find an estimate of how many grapefruits Lily purchased knowing the heaviest and the lightest weight of the set. We can find the average value by using the two extreme values:

$\displaystyle \bar x=\frac{1.3+1.7}{2}=1.5$

If each grapefruit weighed 1.5 pounds, then we can estimate the 22.17 pounds of them will contain

$22.17/1.5\approx 15\ \text{grapefruits}$

Find the difference between each number:

-24/4 = -6

144/-24 = -6

The next number is multiplied by -6

You have the first 4 terms

5th term = -864 x -6 = 5184

6th term = 5184 x -6 = -31,104

7th term = -31,104 x -6 = 186,624

8th term = 186,624 x -6 = -1,119,744
