Answer:
=
Step-by-step explanation:
The fractions are equal because we can simplify 3/6 to 1/3 as their biggest common divisor is 3
and
we can simplify 2/4 to 1/2 as their biggest common divisor is 2
So we are using the common divisor to simplify both fractions to solve this problem.
To factor this you need values that add up to 2 and multiply to -15
So you get 5,-3 then you put it into your equation for you b value
X^2+5x-3x-15
Then you can factor by grouping
X(x+5)-3(x+5)
So your factors are
(X+5)(x-3)
Answer:
4a. S = 300c
4b. S = 2400
Step-by-step explanation:
4a. There are 300 seats in a conference room 'c' so to find the amount of seats there are in total you need to times these values so...
S = 300c
4b. substituting 8 into c gets
S = 300x8
S = 2400
hope this helps!
