So the question is asking: (x-4)(x-2)
because there is a bracket in between the two expressions it means we have to multiply them together: (x-4) x (x-2)
you can break down the question into smaller parts:
x multiply x
x multiply -2
-4 multiply x
-4 multiply -2
here are the answers:
x^2 (means x squared)
-2x
-4x
8 (because when you multiply two negative numbers it makes a positive)
now you put it into an expression (this is expanding):
x^2 - 2x - 4x + 8
to simplify it you collect like terms:
x^2 - 6x + 8
The above is the answer :)

3/5 = 9/15
1/3 = 5/15
Answer:
t = 0
If the loan is to be paid in 0 months, the amount is very large
m = 50
Of the loan is to be paid in an indefinite amount of time, monthly payment would be 50
Step-by-step explanation:
(12000 + 600t)/12t
1000/t + 50
Asymptotes:
t = 0
If the loan is to be paid in 0 months, the amount is very large
m = 50
Of the loan is to be paid in an indefinite amount of time, monthly payment would be 50
Answer:
Step-by-step explanation:
We can solve this question using proportion
Perimeter of the square/Time is takes to unlock
We are told in the question that:
The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.
Hence, the perimeter of the square after 1.5 seconds is:.x = unknown
32/2.5 = x/1.5
Cross Multiply
2.5x = 32 × 1.5
x = 32 × 1.5/2.5
x = 19.2 centimeters
Answer:
D 6
Step-by-step explanation:
Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.
1
× 5 = 
× 5
Multiply 5 by the numerator of the fraction and leave the denominator alone.
× 5 = 
Change back to simplest form.
= 6
