Answer:
12, 17, 24
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12
T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17
T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
7x or just x
Both of them are terms when they have a variable next to it
Answer:
R = 11
C ≈ 69.12
A ≈ 380.13
Step-by-step explanation:
R = d ÷ 2
C = 2πr
A = 2πr²
Answer:
27
Step-by-step explanation:
2(6) + -5(-3)
= 12+15
= 27
I’m not completely sure but I think it’s
4 x 103 2 x 103 = 8 x 106 (btw I don’t know how to write the exponent so the ones next to the 10’s are the exponents)
