Answer:
20 yards of fabric
Step-by-step explanation:
you can find this answer more easily by timing 2 by 8 then timing 1/2 by 8 witch would be 16 and 4 then all you do is add 16 and 4 to get 20
Answer:
4
Step-by-step explanation:
There are 2 outcomes for the first flip and 2 outcomes for the second flip
Multiply
2*2 = 4
4 you will have 2.1 meters of wood left over
Answer:
2x^2 = 6x - 5.
-x^2 - 10x = 34.
These have only complex roots/
Step-by-step explanation:
3x^2 - 5x = -8
3x^2 - 5x + 8 = 0
There are complex roots if the discriminant 9b^2 - 4ac) is negative.
Here the discriminant D = (-5)^2 - 4*-5*8 = 25 + 160
This is positive so the roots are real.
2x^2 = 6x - 5
2x^2 - 6x + 5 = 0
D = (-6)^2 - 4*2*5 = 36 - 40 = -4
So this has no real roots only complex ones.
12x = 9x^2 + 4
9x^2 - 12x + 4 = 0
D = (-12)^2 - 4*9 * 4 = 144 - 144 = 0.
- Real roots.
-x^2 - 10x = 34
x^2 + 10x + 34 = 0
D = (10)^2 - 4*1*34 = 100 - 136 = -36.
No real roots = only complex roots.
