The factorization of x2 + 3x – 4 is modeled with algebra

Mathematics
1 answer:
meriva4 years ago
4 0

Option C: (x+4) and (x-1) are the factors of the equation

Explanation:

Given that the equation is x^{2} +3x-4

We need to determine the factors of the equation.

Splitting the middle term, we get,

x^{2} +4x-x-4

Grouping the terms, we have,

x(x+4)-1(x+4)

Let us factor out the term (x+4), we have,

(x+4)(x-1)

Thus, the factors of the equation are (x+4) and (x-1)

Hence, Option C is the correct answer.

mario62 [17]

Answer:

Henry has a best record for the number of shots made.

Step-by-step explanation:

It is provided that Henry made 0.45 or 45% of his shots.

And Trevor missed 58% of his shots, i.e. Trevor made 42% of his shots.

There is no information about Allison's and Arthur's probability of making the shot.

So, only based upon Henry and Trevor, it can be seen clearly that Henry has a best record for the number of shots made.

Why can’t one of the names be PNM, or MPN for the plane? But MNP can? What’s the difference, and why?
Savatey [412]

The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.

For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.

How do you solve <br> 8|x+2|-6=5|x+2|+3
sergejj [24]

Answer:

x = 1 or x = -5

Step-by-step explanation:

Solve for x over the integers:

8 abs(x + 2) - 6 = 5 abs(x + 2) + 3

Subtract 5 abs(x + 2) - 6 from both sides:

3 abs(x + 2) = 9

Divide both sides by 3:

abs(x + 2) = 3

Split the equation into two possible cases:

x + 2 = 3 or x + 2 = -3

Subtract 2 from both sides:

x = 1 or x + 2 = -3

Subtract 2 from both sides:

Answer:  x = 1 or x = -5
