Answer: b. (x−4)(x−10)

Step-by-step explanation:

Let's factor x^2−14x+40

x^2−14x+40

The middle number is -14 and the last number is 40.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -14

Multiply together to get 40

Can you think of the two numbers?

Try -4 and -10:

-4+-10 = -14

-4*-10 = 40

Fill in the blanks in

(x+_)(x+_)

with -4 and -10 to get...

(x-4)(x-10)

Answer:

(x−4)(x−10)

Given A(2,14), B(2,3), C(4,2) and D(14,2) what about AB?
stepan [7]
Answer - 11

I’m assuming you’re trying to find the line AB (basically the distance between point A and B). If that’s the case, since they both have the same x vale, subtract their y values. 14-3 gives you 11, which is the length of line AB
