The formula S = SA
6 gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a
cube with a surface area of 180 square meters than a cube with the surface area of 120 square meters?

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

60: 45 =12: 9 =4: 3 so the answer is 4: 3
