Answer:

actors of x2−9x+20 are (x - 4) and (x - 5)

Step-by-step explanation:

It is given that,

p(x) =x2−9x+20

<u>Factorize using splitting method</u>

p(x) =x2−9x+20

20 = 5*4  and 5+4 = 9

p(x) = x2−4x - 5x + 20

  = x(x -4) -5x(x - 4)

  = (x - 4)(x - 5)

Therefore factors of x2−9x+20 are (x - 4) and (x - 5)

How do you write 1.92 x 10 0
nordsb [41]
Im guessing your saying how do you write 1.92 x 10 when you multiply you dont need to line up your decimals but it would lookm something like this:
1.92
x 10

and if it was 1.92 and 10.0 it would look like this

1.92
x 10.0

the deimals dont line up because you are multipling but if you were adding or subtrcating then you would have to line it up but not in this case

If a person wanted to purchase his or her dream car, and keep it for many years, is leasing or buying the better option? Why
Pani-rosa [81]

Answer:

Leasing a car is the better option if they only want to keep it for a certain amount of years. This is because with leasing you are only paying the depreciation of the car instead of the buying price. Also, it benefits people that can't pay the down payment for the car.

Nikolay [14]

Answer:

Step-by-step explanation:

a) a^3-64b^3

=(a)^3-(4b)^3

=(a-4b)(a^2+4ab+16b^2)

b) 3x^3-81y^3z^6

=3(x^3-27y^3z^6)

=3{(x)^3-(3yz^2)^3}

=3(x-3yz^2)(x^2+3xyz^2+9y^2z^4)

c)16a^3b^3-54c^3d^3

=2(8a^3b^3-27c^3d^3)

=2{(2ab)^3-(3cd)^3

=2(2ab-3cd)(4a^2b^2+6abcd+9c^2d^2)

hope u got!!
