10x-5y=15
-5y=15-10x
Y= (15-10x)/-5
Y= -3+2x
The answer is Y= -3+2x. Hope this helps
Answer: I'm assuming you want to know how much surface area his fence is, so 40

Answer:
Step-by-step explanation:
If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.
16x^ = (4x)^2 . . . . a perfect square
49 = 7^2 . . . . . . . a perfect square
-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...
16x^2 -56x +49 = (4x -7)^2
_____
The sign in the binomial factors is the same as the sign of the middle term of the trinomial.
Answer:
60
Step-by-step explanation:
The triangles are similar so corresponding angles will be congruent. We also know this because both angles have two lines marking they are congruent.
