If the plane intersects the cylinder horizontally, the cross section is . if the plane intersects the cylinder slanted between horizontal and vertical, the cross section is . if the plane intersects the cylinder vertically through the cylinder, the cross section is . if the plane intersects the cylinder vertically along an edge of the cylinder, the cross section is .

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

40 x 50 = 2000
