Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42
Answer:
Circumference is the distance from the one end of a circle to another
Answer:
19.6 gallons
Step-by-step explanation:
225/10=441/G
cross multiply
225G=10*441
225G=4410
G=4410/225
G=19.6 gallons of gas
Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.
HOPE THIS HELPED:)
