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:
y^2 + 4y + 3
Step-by-step explanation:
(y + 3)(y + 1)
(y*y) + (y*1) + (3*y) + (3*1)
y^2 + y + 3y + 3
y^2 + 4y + 3
Best of Luck!
If all the dogs weighed the same, 44 would be the mean. The weight would be 44*5=220.
