Answer:

(B) 18.

Step-by-step explanation:

We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).

First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.

We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.

$\text{Perimeter of quadrilateral}=8+1+8+1$

$\text{Perimeter of quadrilateral}=16+2$

$\text{Perimeter of quadrilateral}=18$

Therefore, the perimeter of the given quadrilateral is 18 units.

You can buy 7 pillows at jensen's for the same price that you can buy 6 pillows at harrison's. If one pillow costs $21.21 at har

kotykmax [81]

$21.21 × 6 = $127.26

$127.26 ÷ 7 = $18.18 cost of 1 pillow at Jenson's.

You multiply the cost of the pillow at Harrison's, $21.21, by the amount of pillows you can buy at Harrison's, 6.
Then divide the answer by the amount of pillows you can buy at Jenson's, 7. The final answer is the cost of 1 pillow at Jenson's.
