Answer:
- 25x³
Step-by-step explanation:
Given
(x + 5)(x - 5)x³ ← expand the factors using FOIL
= (x² - 25)x³ ← distribute
=
- 25x³
Answer:
- degree 4
- leading coefficient 18
Step-by-step explanation:
The degrees of the terms in the order they are written (exponent of the variable) are: 0, 4, 3, 2.
The highest degree is that of the second term, so that is the degree of the polynomial, 4.
The leading coefficient is the coefficient of that term: 18.
Answer:
⚪ 4: three right triangles and one acute-angled triangle.
Step-by-step explanation:

To fond the area need to be grassed, find the area of the yard and subtract the area of the pool/patio.
(3x - 5)(4x - 10) =
12x^2 - 30x - 20x + 50 = 12x^2 - 50x + 50 Area of yard
(x + 8)(x - 2) =
x^2 - 2x + 8x - 16 = x^2 + 6x - 16 Area of pool/patio
12x^2 - 50x + 50
- ( x^2 + 6x - 16)
---------------------------
11x^2 - 56x + 66 ft^2 LETTER D
