Sorry none of those answers are right
at least to me it isnt
The pic is blurry, but looks like 18x²-21x-15
(3x-5)(6x+3) is the factored form.
3 and 6 are the factors of 18
-5, 3 or -3, 5 are the factors of -15
I line them up like this
3 -5
6 3
then I multiple them diagonally: 3*3=9, -5*6=-30, the sum of 9 and -30 is exactly -21, the coefficient for x. (If the sum doesn't make -21, I'd switch -5 and 3, or change to -3 and 5 to try again.)
so the factored form is (3x-5)(6x+3)
Answer:
25 students
Step-by-step explanation:
To solve this problem, use cross multiplication:
3x = 75
x = 25
There are a total of 25 students in the class.
Answer: C is the correct answer
Step-by-step explanation:
A. Addition and subtraction are opposites.
b. A number line shows where numbers are in relation to each other. It shows that 0 and 100 are farther apart than 0 and 10.
c. If the number is less than 0 or greater than 0. Less than 0 is negative and greater than 0 is positive.
