Question 3 options:
4a5
−12a5
−4a5
12a5
Answer:
4a5
Step-by-step explanation:
(4a3)(a2)
Remove the brackets. Remember brackets mean to multiply.
4a^3*a^2
4a^3*a^2= 4a^3 + a^2
= 4a^5
Answer:
4a⁵
Step-by-step explanation:
(4a³)(a²)
4a³ × a² = 4a³⁺² = 4a⁵

B) 90 − (8a + 9) = (11 + 2a)
C) (11 + 2a) − 90 = (8a + 9)
D) (8a + 9) − (11 + 2a) = 90
Answer:
B
Step-by-step explanation:
Seeing the above angles we conclude that
(11+2a)+(8a+9)=90 (since they are complementary angles)
So
Subtracting (8a+9) to both sides we get
90-(8a+9)=11+2a
Answer:
The answer is B.) 90 - (8a + 9) = (11 + 2a)
Step-by-step explanation:
90 − (8a + 9) = (11 + 2a)
Complementary angles add to 90°
