First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
Answer:
B. 7x - 5
Explanation
Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;
21x^2 + 13x – 20
= 21x^2 + 28x - 15x - 20
= 7x(3x+4) -5(3x+4)
= (7x-5)(3x+4)
Hence one of the factors is 7x - 5
Answer:
Isosceles
Step-by-step explanation:
isosceles triangles have at least 2 EQUAL sides :)
(22a) 1500 x 1.6 x 2
(22b) DEV 1500 x 1.8=2700 1500 x 1.3=1950 2700+1950=4650 1500 x 1.6 x 2= 4800 4650(Emma) < 4800(Dev)
I strongly suggest to check my work. Good Luck and hoped I helped at least a little (I am very tired and it was almost midnight when I did this sorry for any errors).
