Answer:it will cost $1698

Step-by-step explanation:

You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed. The area of the patio would be

15 × 20 = 300 square feet

It means that it costs $2275 to install 300 square feet of the patio professionally. Therefore, the cost of installing 1 square feet professionally would be

2275/300 = $7.58 per square feet

To estimate the cost of having a 14 by 16 ft, we would determine the total area.

Area = 16 × 14 = 224 square feet.

Therefore, the cost of installing 224 square feet professionally would be

224 × 7.58 = 1697.92

Approximately $1698

What is the slope of the line that passes through the points (12,-8) and (-9,-11)
Sauron [17]
Answer: 1/7


Explanation:

1. Use the formula, y2-y1/x2-x1
Plug in the points, (12, -8) and (-9, -11) into the formula.
Point (12, -8): 12 is the X1 and -8 is the y1.
Point (-9, -11): -9 is the X2 and -11 is the y2
So, -11--8/-9-12

2. -11--8/-9-12= -3/-21= 1/7

I hope this helps!!
