Fractional form: 63/10 or 6 3/10.
Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.
Answer:
Step-by-step explanation:
2(12x^2-x)=15
24x^2-2x-15=0
24x^2-20x+18x-15=p
4x(6x-5)+3(6x-5)=0
(4x+3)(6x-5)=0
x= -3/4 or 5/6
For every one it goes up once, one is added
