ANSWER

or

We have

Since we cannot factor easily, we complete the square.
Adding 2 to both sides give,

Dividing through by 3 gives

Adding

to both sides gives

The expression on the Left Hand side is a perfect square.




Splitting the plus or minus sign gives

Answer:
x=4C/πs^2
Step-by-step explanation:
C=1/4πs^2x
1) Divide both sides by π and s^2:
C/πs^2=1/4x
2) Multiply both sides by the reciprocal of 1/4: (4)
4C/πs^2=x
Answer:

Step-by-step explanation:
From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares
, the remaining unknown angles are equal (
). The sum of the interior angles of a triangle always add up to
.
Therefore:
.
C. The first is a solution, but the second is not.
5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13
5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution
hope i could help
