Step-by-step explanation:
all you have to do is multiply all those numbers together so 0.5 * 4.2 * 2.8 *7 =41.16
the process the exact same for all the other ones they have all your stuff set out for you on each one of the shapes
The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
The way I would do it is: draw a graph and chart it... you should see where it intersects with one of the answers. when in doubt, draw it out
Answer:
Step-by-step explanation:
First, you can reduce it
4(n^2-11n+30)
This should make it easier to work with. But remember, keep the 4 there. You cannot just get rid of it because it would change the value of the equation
Now find factors of 30 that have a difference or ad up to 11.
Factors of 30:
1, 30
2, 15
3, 10
5, 6
Ahh yes, 5 and 6 add to 11
4(n-5)(n-6)
