pls be more cleare
Step-by-step explanation:
type the question properly and clearly
3 is not a factor of 32. Therefore, x will not be a whole number. X is equal to about 10.66
Answer:
10
Step-by-step explanation:
100 ÷ 10 = 10
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
so she saved $20 and that was 40% of the regular price, let's say the regular price is "x".
if 20 is 40%, what is "x" or namely the 100%?
