Answer:
Step-by-step explanation:
The segment addition theorem tells you ...
CD +DE = CE
x^2 +12x = 32 -2x
Subtract the right side to put this in standard form.
x^2 +14x -32 = 0
(x +16)(x -2) = 0
x = -16 or 2
In order for DE to have a positive length, we must have x > 0. So ...
CD = x^2 = 2^2 = 4
DE = 12x = 12(2) = 24
CE = 32 -2x = 32 -2(2) = 28
Answer: Craig's household use of water during the billing period = 129 CFC
Explanation:
Since we have given that
Craig's June water meter's previous reading =6372 CFC
Craig's water meter's present reading =6501 CFC
Craig's household use during the billing period =6501 -6372= 129 CFC
So, we get that
Craig's household use of water during the billing period = 129 CFC
24 girls divided by 6 girls = 4 boys. 3 boys for every girl and there is 6 girls so you would do 4 x 3 = 12 boys.
