Answer:
I think the answer is C but I'm not 100% sure
X + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 195
(Make sure you don't add "x+5" because "x + 0" is an included term.)
5x + 10 = 195
5x = 185
x = 37
Hope this helps!
Circumference = 2 * PI * radius
Circumference = 2 * 3.14159265 * 63
Circumference = 395.841
x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6
Y=2
If you subtract 9-7 you get the answer 2 which makes y=2.
