Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
Every Triangle adds up to 180 degrees
180 - 63 = 117 | 117 - 56 = 61 so x = 61
12y + 3 = 51 so y = 4
(5x²+4x-80)(x²-5x-24)=5x²(x²-5x-24)+4x(x²-5x-24)-80(x²-5x-24)
{distributive property of multiplication}
=5x^4-25x³-120x²+4x³-20x²-96x-80x²+400x+1920
=5x^4-21x³-220x²+304x+1920
This is the answer.
