Answer:

-16, -4

Step-by-step explanation:

x² +20x +100 -36 = 0

x² +20x +64 = 0

x² -Sx +P =0, where S= sum of roots, P=product of roots

so what 2 numbers have

S= -20 and P = 64 , ...that ul be -4, -16

or you can use factoring:

( x+16) ( x+4) = 0

x+16 = 0 , x= -16

x+4 =0, x = -4

or you can do quadratic equation, or graph ...

Answer: The Answer is:

Fraction form: x= -32/11

Decimal form: x= -2.90909....

Step-by-step explanation:

1. Add similar elements: 2x+20x=22x

22x+100=36

2. Subtract 100 from both sides:

22x+100-100=36-100

3. Simplify:

22x=-64

4. Divide both sides by 22:

22x÷22=-64÷22

5. Your Answer:

x= -32/11

The base of a solid crate has an area of 6 square meters.The height of the crate is 4 meters. What is the volume of the crate?
professor190 [17]

Given is the base area of a solid crate, B = 6 square meters.

Given is the height of the solid crate, H = 4 meters.

We know the formula for volume of any solid is given as follows :-

(Volume of the solid) = (Base area of the solid) x (Height of the solid).

Volume = B x H.

Volume = (6 square meters) x (4 meters).

Volume = 24 cubic meters.

Hence, the volume of the solid crate would be 24 cubic meters.

Really stuck on this one. Which of the following are ordered pairs for the equation y =x - 4?
mamaluj [8]

Answer: Choice D

(0,-4) (4,0) and (-1,-5)

===========================================================

Explanation:

Plug in x = -4

y = x-4

y = -4-4

y = -8

The point (-4,-8) is on the line instead of (-4,0). This rules out choice A and choice B.

Now plug in x = 1

y = x-4

y = 1-4

y = -3

We get (1,-3) instead of (1,5). So we can rule out choice C.

The answer must be choice D.

The graph is below.
