Answer:

(x+1)(x+30)

Step-by-step explanation:

Area is equal to length * Width so you have to find what two expressions multiplied together equal the quadratics equation.

There are several ways to do this, but i would recommend factoring the expression. To do so, find factors of the third term that when added, equal the second term.

In this scenario

X^2 + 31x + 30

find factors of 30:

1,30

2,15

3,10

5,6

In this scenario it is clear that 1 and 30 are the two factors that equal 31

the final answer would be written as

(x+1)(x+30)

and when these two terms are multiplied out together you get your initial area

The values in a dataset are 3.5, 2.5, 2.5, 3.5, and 3.0. If Xbar (sample mean) = sigma X / n, what is the mean for the sample?

RideAnS [48]

Answer:

$\bar x = 3.0$

Step-by-step explanation:

Given

$x: 3.5, 2.5, 2.5, 3.5, 3.0$

Required

The sample mean

This is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}$

$\bar x = \frac{15.0}{5}$

$\bar x = 3.0$

Answer:

y = x - 2 could not be the function equation.

Step-by-step explanation:

The function with an input of 3 has an output of 5.

So, y = 2x - 1 can be the function as y(3) = 2 × 3 - 1 = 6 - 1 = 5.

Now, y = x + 2 can also be the function as y(3) = 3 + 2 = 5

Again, y = 3x - 4 can also be the function as y(3) = 3 × 3 - 4 = 9 - 4 = 5

But y = x - 2 can not be the function as y(3) = 3 - 2 = 1 ≠ 5

Therefore, y = x - 2 could not be the function equation. (Answer)
