Answer:
9
Step-by-step explanation:
Solving the equation on the left we get
(x-9)^2
Answer:
Number 1 and 2
Step-by-step explanation:
For number 1, you have to distribute the 2 so 2*x=2x, and 2*4=8
That makes 2x+8 and number 2 is the only answer
Answer:
A. I can't quite see the question, but I'm pretty sure it's A
Step-by-step explanation:
Sin(A) = 1/3
Sin^2(A) + Cos^2(A) = 1
(1/3)^2 + cos^2(A) = 1
1/9 + cos^2(A) = 1
cos^2(A) = 1 - 1/9
cos^2(A) = 8/9
cos(A) = √(8/9)
√8 = √(2 * 2 * 2) = 2√2
√9 = 3
cos(A) = 2√2/3
