Rewrite the equation by completing the square.
x^{2}-14x+49 = 0 please help

(x-7)² = 0

Step-by-step explanation:

Normally, you'd want to rewrite ax²+bc+- as a(x+d)²+e=0, but in this case there is no e necessary, since (x-7)² already equals x²-14x+49=0.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
