The shapes are in the picture!

The roof of a house is in the shape of a house is in the shape of a square pyramid. The slant height of the pyramid is 17 feet, and the length of each side of the square is 30 feet. What is the lateral surface area of the pyramid in square feet?

A. 1,920 feet radius 2
B. 2040 feet radius 2
C. 1,020 feet radius 2
D. 1,410 feet radius 2​

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
