Answer:
the first one mate
Step-by-step explanation:
To solve for Pi do the following:
C = 2Pi • r
C/2r = Pi
The solution would be Pi equals C over quantity 2 times r.
7y - 23 + 23x -16 + 8x - 21
31x + 7y - 60
What is the original problem equal to? You can't go any further unless you know.
The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.
(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab
x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.
Thus the answer to this question is option C
