The first pair because one is a triangle and the second is a acute triangle
Sounds like 18 servings to me.
6 quarters go into 1.5
6 x 3 is 18 so 18 servings.
Answer:
x=2
Step-by-step explanation
5x-10=0
fist add 10 to both sides to cancel the -10 on the left side
5x=10
then divide both sides to cancel the 5 in front of the x and to get the x all by itself
x=2
and then you have your answer!
Find factors of -5 that, when added together, will give 4
x² + 4x - 5
x 5
x -1
(x + 5)(x -1)
Using the FOIL method (First, Outside, Inside, Last), we can get the question again.
x(x) = x²
x(-1) = -x
5(x) = 5x
5(-1) = -5
x² - x + 5x - 5
x² + 4x - 5
(x + 5) (x - 1) is your answers
however, i believe it is only asking for one. Therefore, because (x - 1) is a choice, (x - 1) should be your answer
hope this helps
