Could someone help me?

1.(x−6)(x−9)

2.2(x2−14x+15)

3.x2−18x+88

Step-by-step explanation:

here explain

The middle number is -15 and the last number is 54.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -15

Multiply together to get 54

Can you think of the two numbers?

Try -6 and -9:

-6+-9 = -15

-6*-9 = 54

Fill in the blanks in

(x+_)(x+_)

with -6 and -9 to get...

(x-6)(x-9)

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

answer: 12
