If I'm right, 14/3 m and 2/3 m are like terms, so -14/3m+2/3m= -12m. Your answer is then 12-12m
Answer:
92
Step-by-step explanation:
Determine the number of solutions using the discriminant D=b^2-4ac
D=m^2-4•3•(-3)
Calculate the product D=m^2+36
Since D > 0 for any value of m
The quadratic equation has 2 real roots.
Answer:
8a+2b+c
Step-by-step explanation:
13a-4b+8c
-(5a-6b+7c)
simplify second equation: -5a+6b-7c (multiplying -1 by each number)
now solve
13a-4b+8c
-5a+6b-7c
= 13a-5a-4b+6b+8c-7c (combining both equations, and like terms)
solve:
8a+2b+1c
= 8a+2b+c
The GCF is 7.
Therefore, divide both denominator and numerator by 7.
<u>21 ÷ 7</u>
56 ÷ 7
= 3/8
