Factor the trinomial below.
x^2 - 13x + 40
a. (x - 4)(x + 10)
b. (x - 5)(x + 8)
c. (x - 4)(x - 10)
d. (x - 5)(x - 8)

D

after you use the FOIL method (just multiplying everything) you'll get x^2 - 8x - 5x + 40. now just add the like terms

its D

Dont even trip I just did the test ;)

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

hey there : ) your answer would be a.
