Answer:
(x + 6)(x - 2) = x² + 4x - 12
(x + 2)(x - 8) = x² - 6x - 16
(x + 6)(x - 6) = x² - 36
(x - 5)(x - 1) = x² - 6x + 5
(x - 4)(x - 10) = x² - 14x + 40
(x + 2)(x + 5) = x² + 7x + 10
Step-by-step explanation:
Use FOIL.
(x + 6)(x - 2) =
F - first: x × x = x²
O - outer: -2 × x = -2x
I - inner: 6 × x = 6x
L - last: 6 × -2 = -12
(x + 6)(x - 2) = x² - 2x + 6x - 12
Now, combine like terms.
(x + 6)(x - 2) = x² + 4x - 12
(x + 2)(x - 8) = x² - 6x - 16
(x + 6)(x - 6) = x² - 36
(x - 5)(x - 1) = x² - 6x + 5
(x - 4)(x - 10) = x² - 14x + 40
(x + 2)(x + 5) = x² + 7x + 10

Answer:
14. 4 + x - 2
15. 8k - 3k
16. 5 + 2y + 15
Step-by-step explanation:
14. "sum" means adding, "minus" means subtract
sum of four and x: 4 + x
minus two: 4 + x - 2
15. "product" means multiplying, "decreased by" means subtract, "times" means multiply
the product of k and 8: 8k
three times k: 3k
the product of k and 8 decreased by three times k: 8k - 3k
(Depending on what the question is asking, you may or may not need to simplify this to 5k (8k - 3k = 5k))
16. "more" means add, "plus" means add, "twice" means multiply by two
five: 5
plus twice y: 5 + 2y
fifteen more: 5 + 2y + 15
The volume of the rectangular prism is 1120 yd³.
<h3>What is a prism?</h3>
A prism is a solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
To calculate the volume of the rectangular prism, we use the formula below.
Formula:
- V = LWH.......... Equation 1
Where:
- V = Volume of the rectangular prism
- L = Length of the prism
- W = Width of the prism
- H = Height of the prism.
From the question,
Given:
- L = 14 yards
- W = 8 yards
- H = 10 yards.
Substitute thee values into equation 1
Hence, The volume of the rectangular prism is 1120 yd³.
