What is the surface area? 10 cm 7 cm 3 cm square centimeters

242 cm²

Step-by-step explanation:

The equation for surface area is 2 (wl+hl+hw). In this case, we just have to multiply the three values of 10 cm, 7 cm, and 3 cm.

(10 x 7) x 2 = 140

(10 x 3) x 2 = 60

(3 x 7) x 2 = 42

140 + 60 + 42 = 242

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
