Well 25% is the same as .25 or 1/4. So first you need to add X and Y so X+Y and since it is both you choose D
If this is factoring(I dont know what you’re asking,) take out a -4 and x^2
You get -4x^2(2x+5)
I think the equation would be -(1/2)
Answer:
b = 5√6
c = 10√5
Step-by-step explanation:
This is a 30-60-90 triangle
the hypotenuse is always twice the short leg
c = 2(5√2)
c = 10√5
The long leg is alway √3 times the short leg
b = √3(5√2)
b = 5√6
