Answer:
The measurement around the circle
Step-by-step explanation:
ANSWER
The correct answer is

EXPLANATION
The expression given to us is,

We plug in

. That means we substitute 12 wherever we see x to obtain,

We simplify the parenthesis first to obtain,





Hence the expression evaluates to
C = 3.5t....when t = 15
c = 3.5(15)
c = 52.50 <==
Answer:
x=20
Step-by-step explanation:
The Pythagorean theorem is
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse.
The legs are x and 15 and the hypotenuse is 25
x^2 + 15^2 = 25^2
x^2 +225 = 625
Subtract 225 from each side
x^2 +225-225 = 625-225
x^2 = 400
Take the square root of each side
sqrt(x^2) = sqrt(400)
x = 20
