4x-5y=0 8x+5y=-60 what is the answer by substitution or elimination?

1 answer:

7 0

The answer is -5, -5 added by 5 cancels each other out. Then when you add 4x + 8x, you get 12x. So when you do 12x= -60, you get -5.

Find the product (x-y)(6x+4y)

Mazyrski [523]

The product means you multiply, so:
-y × 6x = -6xy
-y × 4y = -4y²

x × 6x = 6x²
x × 4y = 4xy

= -2xy - 4y² + 6x

I hope this helps!

50a3b-8ab factor the expression completely. part a: factor out the gcf (5 points) part b: factor the difference of perfect squar

dem82 [27]

Answer:

Step-by-step explanation:

50a³b = 2⋅5²a³b

8ab = 2³ab

GCF = 2ab

50a³b - 8ab = 2ab(5²a² - 2²)

5²a² - 2² = (5a - 2)(5a + 2)
