Answer:
c = 3 c = -1/2
Step-by-step explanation:
(4c-5)^2= 49
Take the square root of each side
sqrt((4c-5)^2)= ±qrt(49)
4c-5 = ±7
Separate into two equations
4c-5 = 7 4c-5 = -7
Add 5 to each side
4c-5+5 = 7+5 4c-5+5 =-7+5
4c =12 4c = -2
Divide by 4
4c/4 = 12/4 4c/4 = -2/4
c = 3 c = -1/2
Answer:
c = -½, 3
Step-by-step explanation:
(4c - 5)² = 49
4c - 5 = +/- 7
4c - 5 = 7
4c = 12
c = 3
4c - 5 = -7
4c = -2
c = -½
