Answer:
x = 10
Step-by-step explanation:
If f(x) equals 3x-7 and also equals 23, then you can set 3x-7 equal to 23
3x - 7 = 23
3x = 30
x = 10
(12(18))+(13(13))= 216ft squared +169 feet squared = 385 ft squared
385feet squared ($3.50)=$1,347.50
Answer:
It isn’t true that corresponding cross-sections have the same area.
Step-by-step explanation:
I got it off of khan academy.
Add 2 to both sides
g + 2 = -2x
Divide both sides by -2
-g + 2/2 = x
Simplify g + 2/2 to 1 + g/2
-(1 + g/2) = x
Simplify brackets
-1 - g/2 = x
Switch sides
<u>x = -1 - g/2</u>
