-9y-15x ---- -3
The correct classification of x2 15x is a monomial.
15x because 5 cant go into 15x look at it like this 5 is a bird and 15x is a bee birds and bees are not the same so you cant add them the answer is 15x-5 good luck
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
Use algebra. 12x+30=15x-20. Add 20 to both sides. 12x+50=15x. Subtract 12x from both sides. 50=3x. Divide both sides by 3. 16.666...=x

It is: -5x-20 when simplified
(x+20)(x-5) x=5 or -20
distributive
15x-17
The distributive property states that a(b + c) = ab + ac. This only works in your case if you meant to write 15(x + 20). That would equal 15x + 300.
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
You're looking for factors of 100 that differ by 20. (x + 5)(x - 20)
35x + 15x = 50x
