Fill in the empty spaces with monomials that make each equality into an identity.
(5x + ... )(5x − ...) = ... −0.49y^4

  (5x +0.7y^2)(5x -0.7y^2) = 25x^2 -0.49y^4

Step-by-step explanation:

We know the product of a sum and difference can be the difference of squares. The term on the far right is a perfect square: -(0.7y^2)^2.

The binomials on the left look like a sum and difference, so we can fill this in as ...

  (5x +0.7y^2)(5x -0.7y^2) = 25x^2 -0.49y^4

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

answer is c

step-by-step explanation:

81/12=324/x

x=48
