Answer:
x³ - 2x² + 2x - 2
Step-by-step explanation:
f(x) - g(x)
= 2x³ - 4x² + 2 - (x³ - 2x² - 2x + 4) ← distribute by - 1
= 2x³ - 4x² + 2 - x³ + 2x² + 2x - 4 ← collect like terms
= x³ - 2x² + 2x - 2
Answer:
Step-by-step explanation:
Givens
Length = a
Width = a + 3
Formulas
P = 2L + 2w
Area = L * w
Solution
Perimeter
P = 2L + 2w
P = 2*a + 2(a + 3) Remove the Brackets
p = 2a + 2a + 6 Combine
<u><em>P = 4a + 6</em></u>
Area
Area = L * w
Area = a (a + 3)
<u><em>Area = a^2 + 3a</em></u>
