Pretty sure it's (x-7)^2 - 25.
Answer:
A
Step-by-step explanation:
1.9 about 2, and 4.4 is about 4.
2x4=8
So it is safe to say between 4 and 10.
162/60 = 2.7 heartbeats per second
1. 3x-6+2x+108+88=360
5x=170
x=34
2. figure B
63 + 36...there is a common factor of 9
9(7 + 4) <== this is equivalent
63 + 36...there is a common factor of 3
3(21 + 12)...but this is not an answer choice...but it is equivalent
