Determine the factors of 3x2 + 10x − 8. (Which is the right answer?)
1 answer:
ANSWER

EXPLANATION
The given quadratic trinomial is

Comparing to the general quadratic trinomial:

We have a=1, b=10 and c=-8

The factors of -24 that adds up to 10 are -2 and 12.
We split the middle term to obtain;

Factor;

Factor further;

The last option is correct.

13. 44 + 34 = 78
14. 101 - 1 = 100
15. -539 ???
16. 15 ??
17. |-435| = 435
Since ur using r as a variable the answer is r = 7.
The answer is 0.91 because it is
a = 180 - 112
a = 68°
b = 112°
c = a = 68°
√(3*15)=√45=√[5*3^(2)]=3√5
