Answer:
4(x + 2)
Step-by-step explanation:
Factor out common factors from each term. Note the factors for each number
4: 1, 2, 4
8: 1, 2, 4, 8
The largest factor for each is 4, and so divide 4 from both terms.
(4x + 8)/4 = (x + 2)
4(x + 2) is your factored expression.

Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
= 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
Answer:
x(θ) = 5 tan θ
Step-by-step explanation:
Given that:

we are to state the trigonometric substitution to be used to find the indefinite integral.
Suppose u is the variable and a is the constant
u = x
a = 5
So; (a² + x²)ⁿ
which is a trigonometric substitution for x = a tanθ
Then,
x(θ) = 5 tan θ
