Answer:

(x+4)

Step-by-step explanation:

Solve by factoring. Think about what numbers multiply to be -36 (the last term) BUT also subtract/add up to be -5, which is the middle term. The answer to this is 4 and -9. Therefore, the two factors are (x-9)(x+4)

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

In simplified exponential notation, the expression x^3•x^-4•x=
alexandr1967 [171]
Since all of the bases (x) are equal you just add the exponents.

(The x has an exponent of 1)

3 + -4 + 1

-1 + 1

0

Since the answer is 0 it is x^0

And any number or variable set to the power of 0 equals 1, therefore...

ANSWER: x^3 • x^-4 • x = 1

Hope this helps!

What are all the factos of 36 ​
oksano4ka [1.4K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

{1, 2, 3, 4, 6, 9, 12, 18, 36}

»»————- ★ ————-««  

Here’s why:

A factor is a whole number that is multiplied by another to have a product have another number.

⸻⸻⸻⸻

The Factors Are:

  • 1 (1 * 36 = 36)
  • 2 (2 * 18 = 36)
  • 3 (3 * 12 = 36)
  • 4 (4 * 9 = 36)
  • 6 (6 * 6 = 36)
  • 9 (9 * 4 = 36)
  • 12 (12 * 3 = 36)
  • 18 (18 * 2 = 36)
  • 36 (36 * 1 = 36)

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer:

x=0

Step-by-step explanation:

y=-5x -6

10x + 2y = -12

Substitute y into the equation:

   10x+2(5x-6)=-12

Use distributive property

   10x+10x-12=-12

Add like terms

   20x-12=-12

Add 12 to  both sides of the equation

   20x=0

divide each side by 0

   x=0
