Answer:
43
Step-by-step explanation:
7*3+22
3ab...when a = 2 and b = 3
(3)(2)(3) = 6(3) = 18
Answer:
f(3) = 68
Step-by-step explanation:
→ f(1) = 2 ⇒ f(2) = f²(2 − 1) + 4
= f²(1) + 4
= 2² + 4
= 8
………………………………………………
→ f(2) = 8 ⇒ f(3) = f²(3 − 1) + 4
= f²(2) + 4
= 8² + 4
= 64 + 4
= 68
Answer:
4x^2 + 11x - 20
Step-by-step explanation:
- area is width X height
- multiply the width (4x - 5) and the height(X + 4)
- I always imagine a multiplication grid for this kind of problem, with X and +4 at the top and 4x and -5 going down, and then combine terms
- you get 4x^2 + 11x - 20
