i need help factoring polynomials and knowing the steps to reach the answer. 1) x² - 7x + 10 as well as 2) 6r² + 19r - 20

1)  (x-2)(x-5)

2) (6r-5)(r+4)

Step-by-step explanation:

1)

It will just be x since the coefficient is 1

To figure out the second number you need to think of the multiples of 10.  

So either 2 and 5 or 1 and 10.  Since 2 and 5 add to 7 it's them.  

They're negative since 7 is and can still make a positive 10.

2)

This one is more just plugging and guessing to see which on works.

Find the multiples of both 6 and 20, afterwards plug in the multiples til you get 19 in the final product.  

Since 20 was negative the one of the numbers would be negative.  

I can't explain it lol

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

answer: i think it's a
