Answer:
b. 10a³ - 11a - 3
Step-by-step explanation:
1. Expand 3(a³ - 2a - 5)
= 3a³ - 6a - 15
2. Add 7a³ - 5a + 12 and 3a³ - 6a - 15
7a³ + 3a³ = 10a³
-5a + -6a = -11a
12 + -15 = -3
3. Answer: b. 10a³ - 11a - 3
Answer:
108
Step-by-step explanation:
let the base = x
height = 1.5x
18=1.5x
x=18/1.5 =12ft
thus,
height = 18ft
base=12ft
area = 1/2*(height*base)
=0.5*12*18
=108 feets square
