Answer:
168.61
Step-by-step explanation:
C=2*Pi*R
C=2*3.14*26.85
C=6.28*26.85
C=168.61
-7 replaces the t so it would be
w(-7) = -2(-7)+1
= 14+1
= 15
Answer:
Okay so I am assuming you mean the third part?
Step-by-step explanation:
Pretty simple. So you see that the varible x^2 does not have a number in front of it, so there is no extra dividing.
A formula for a perfect square is (x^2)+2xy+y^2
Take 10 and divide it by 2.
10/2=5
You have Y. Finding the third part is squaring Y.
5^2=25
Therefore, the third part of the perfect square is 25. If you want to find Y, look at the stuff above.
-2(4y+6) = 52
-8y -12 = 52
Add 12 on both sides
-8y= 64
Y= -8
Hope this helps!
