Answer:
9/16 of the students
Step-by-step explanation:
first you can simplify 15/20 to 3/4
you can simplify 12/16 to 3/4
3/4*3/4=9/16
4. It has exactly 2 parallel sides.
Answer:
C.
Step-by-step explanation:
I think the equation meant ?
Anyways, to factor these kinds of quadratic, keep into consideration:
ONLY if:
Start off by finding factors of c, which in this case, -18:
±(1, 2, 3, 6, 9, 18)
If one of the numbers is negative then the other number must be positive.
Find which two factors will sum up to b, which in this case, is 3.
The only two factors that work are 6 and -3.
Replace them into the factored form:
Answer:
-2±2i√5 / 3
Step-by-step explanation:
You can't factor this equation, so you use the quadratic formula to solve it, which is
-b±√b-4ac/2a
