A common way to simplify this problem would be to use an area model, or the distributive property. Using the distributive property does not require any drawing, so here goes.
(x-3)(x²+7x-8) Distribute by multiplying each of the terms in the first set of parentheses by every term in the second set of parentheses.
x³+7x³-8x-3x²-21x+24 Then combine alike terms.
8x³-3x²-29x+24 Is your final answer.
The temperature went up 29°C, which represents a positive 29. Then the temperature fell 29°C, which represents a negative 29. The average temperature rose and fell the same amount. The absolute values are the same, so the difference is 0.
Answer:
B)
Step-by-step explanation:
(a-4)²-a-4
a²-8a+16-a-4
a²-9a+12
Answer:
120 square feet
Step-by-step explanation:
Area = length x width
Insert the two values. Width will represent height.
Area = 12 x 10
Solve.
