Answer:
1. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Step-by-step explanation:
Assume Josh made X cupcakes; Alice made Y cupcakes; Tom made Z cupcakes.
Josh made 10 more cakes than Alice so,
X = Y + 10 ---- 1st Eqn.
Alice made 8 more than Tom so,
Y= Z+8 --- 2nd Eqn.
Total cakes = 62 so,
X+Y+Z = 62 ---- 3rd Eqn.
by solving three equations we get X= 30; Y= 20; Z=12.
So Tom made 12 cupcakes
Answer:
-5x-4
Step-by-step explanation:
You first have to combine like terms. (-6x + x) + (+3 -7) = -5x-4
Answer:
7 + x/8
Step-by-step explanation:
sum of 7 and Q(quorient)
7 + Q
quotient of x and 8
x/8
plus 7
7 + x/8
Hi there, 3 feet + 2 feet= 5 feet and 9 inches + 11 inches = 20 inches.
Therefore the answer is 5 feet, 20 inches
