What is the factored form of the polynomial?

Mathematics
1 answer:
Reptile [31]3 years ago
6 0

Answer:

(x + 4)(x + 5)

Step-by-step explanation:

Given

x² + 9x + 20

Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)

The factors are + 4 and + 5, since

4 × 5 = 20 and 5 + 4 = 9, hence

x² + 9x + 20 = (x + 4)(x + 5)

mylen [45]

Answer:

The highest possible price of a sweater is $28.33

Step-by-step explanation:

We already know that price j of jeans is $35.Let's say Mrs.Smith buys 3 sweaters for p dollars each, and since her budget is $120 we have the inequality:

3p+j\leq 120\\ \\\\=3p+35\leq 120

Therefore

p\leq 28.33

Thus the maximum price of a sweater is $28.33

The sum of the measures of two adjacent angles is 72 degrees. The ratio of the smaller angle to the
Goryan [66]

Answer:

The larger angle is 54°

Step-by-step explanation:

Given

Let the angles be: θ and α where

θ > α

Sum = 72

α : θ = 1 : 3

Required

Determine the larger angle

First, we get the proportion of the larger angle (from the ratio)

The sum of the ratio is 1 + 3 = 4

So, the proportion of the larger angle is ¾.

Its value is then calculated as:.

θ = Proportion * Sum

θ = ¾ * 72°

θ = 3 * 18°

θ = 54°
