-4y - x - (3y - 9x)...distribute the - thru the parenthesis
-4y - x - 3y + 9x....now combine like terms
8x - 7y <== or -7y + 8x
Its 30% because if you take 103 put it in the calculator and divide by 100 you get 1.03 and multiply that time 30 you get 30.9 thats how you find percent
Answer:
Yes, is a right triangle
Step-by-step explanation:
To know if you can build a right triangle with those sides we have to make the following equality
h² = l1² + l2²
The hypotenuse is always the longest side so it should be 39
we check the equality of the equation
39² = 15² + 36²
1521 = 225 + 1296
1521 = 1521
Equality was fulfilled so it is a right triangle
