Step-by-step explanation:
Both equations use x squared
Answer:
The common facor is x-3.
Step-by-step explanation:
The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.

I would have to say J.
Step-by-step explanation: Now a square has 4 sides, all equal as well. (I am on PC so I cant do the little 2 on J.) so 2 times little 2 is 4, because with these for example, 2 times little 3 would be 2 times 2 times 2. So 2 times little2 -9 is the most reasonable answer!

What is the perimeter of the figure on the coordinate plane below?
Answers
Answer:
26 units
Step-by-step explanation:
im not sure if this will help but i counted the spaces and added the halves
The perimeter of the given figure on the coordinate plane is 56 units.
What is perimeter?A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.
Now from given figure, the following length of the sides is given,
9 units
4 units
4 units
8 units
11 units
3 units
2 units
15 units
Now since we know that,
Perimeter = Sum of lengths of all the sides
⇒ Perimeter = 9+4+4+8+11+3+2+15
⇒ Perimeter = 56 units
Thus, the perimeter of the given figure on the coordinate plane is 56 units.

step by step thanks you
Answers
The answer is a and b.
Here's the way to check:
Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.
For a, 512 - 8 = 504
The pattern from a is each number is increased by 7. So,
504 ÷ 7 = 72
The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.
Repeat the above steps for b and c:
512 - 23 = 489
489 ÷ 3 = 163
It can be divided without remainder, 512 appears in this sequence.
512 - 12 = 500
500 ÷ 12 = 41.66666
Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.
However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

Answers
Answer:
2
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The slope is equal to the rise/run of the line, or in other words, the number of units it travels up over the number of units it travels right. We can see on the graph that for every time it travels right 1 unit it travels up 2 units, so the rise/run is 2/1. 2/1 is equal to 2, so therefore, the slope of the line is 2.

Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

What is the value of x?
11 (9 - 2x) = -(12x + 11)
Answers
Explanation: 99-22x=- 12x - 11
Collect like terms: -22x + 12x = -11 - 99
Divide both sides: -10x = -110 by -10
Answer:
x=11
Step-by-step explanation:
First Distribute 11 to 9 and -2x
Then distribute the negative to 12x and 11
Then calculate like terms
-22x + 12x = -11 -99 which comes out to -10x=-110
Then divide each side by -10
Your answer will then be x=11
