Answer:
a. 254.34, b. 56.52
Step-by-step explanation:
a. A = πr^2,
A = 3.14(9^2)
A = 3.14*81
A = 254.34
b. C = πd
C = 18*3.14
C = 56.52
Answer:
65,527
Thank you and please rate me as brainliest as it will help me to level up
The coefficient of y = 3
coefficient = the constant in front of a variable
Constant means that the number will not change.
hope this helps
The correct order is: 0.25, 4/8=0.5 so they go above each other, 3/4
Answer:
x = 2.
Step-by-step explanation:
(Brainliest?)
So log3(2x-1)+log3(x+7)=3 = log3(3^3) So (2x- 1)(x+7) = 27..... 2x^2+13x - 34 =0 (2x+17)(x - 2) = 0 ..so x = 2 or - 17/2. The solution x = - 17/2 is rejected since we cannot have log 3(2*- 17/2 - 1),a negative number. So the answer is x = 2.
