Answer:
Your answer is A
Step-by-step explanation:
A = pi*r²
A = 3.14*70²
A = 3.14*4900
A = 15386
Y = -3x + c
Using (1,-5):
-5 = -3(1) + c
c = -5 + 3(1) = -2
Therefore:
y = -3x - 2
Answer:
Step-by-step explanation:
I'm thinking cu
(x+6)² = y
(x+6)(x+6)=y
x²+12x+36=y
Bidmas, division before addition3x(3+12/3)-4 = 3x(3+4)-4 = 21-4 = 17
