Answer:
2 or 4
Step-by-step explanation:
Since I do not quite understand what you mean by X X, I could think of two answers. If you are doing 5 times X=20, then X = 4, but if you are trying to do 5 times x times x, then x=2.
Answer:
140
Step-by-step explanation:
20+4(s)=
20+4(30)=
20+ 120=
140
1000+9 x 100 + 9 x 10 + 3 x 1 or 1000 + 900+ 90 + 3
Answer:
- (-16x² +10x -3) +(4x² -29x -2)
- (2x² -11x -9) -(14x² +8x -4)
- 2(x -1) -3(4x² +7x +1)
Step-by-step explanation:
I find it takes less work if I can eliminate obviously wrong answers. Toward that end, we can consider the constant terms only:
- -3 +(-2) = -5 . . . . possible equivalent
- -10 -5 = -15 . . . . NOT equivalent
- 3(-5) -2(5) = -25 . . . . NOT equivalent
- -9 -(-4) = -5 . . . . possible equivalent
- -7 -(-5) = -2 . . . . NOT equivalent
- 2(-1) -3(1) = -5 . . possible equivalent
Now, we can go back and check the other terms in the candidate expressions we have identified.
1. (-16x² +10x -3) +(4x² -29x -2) = (-16+4)x² +(10-29)x -5 = -12x² -19x -5 . . . OK
4. (2x² -11x -9) -(14x² +8x -4) = (2-14)x² +(-11-8)x -5 = -12x² -19x -5 . . . OK
6. 2(x -1) -3(4x² +7x +1) = -12x² +(2 -3·7)x -5 = -12x² -19x -5 . . . OK
All three of the "possible equivalent" expressions we identified on the first pass are fully equivalent to the target expression. These are your answer choices.

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:
Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?
Answer: 2 full gas cans
Step-by-step explanation:
From the image, we have the following dimensions:
length, l = 15.4 inches (in)
width, w = 10 in
height, h = 3 in.
The volume of the gas tank (which is rectangular) is given as:
NB: The unit of volume is cubic units. In this example, it is cubic inches.
The gas can being used to fill the tank holds 1 gallon of gas = 
The total volume to be filled is 
of gas.
So, it will take 
full gas cans to fill the go cart's gas tank.
Therefore, the answer is 2.
