20 and 7 Because 4x5 = 20
Answer:
23.7
Step-by-step explanation:
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.
Answer: 107
Step-by-step explanation:
1 Remove parentheses.
16x-80<2716x−80<27
2 Add 8080 to both sides.
16x<27+8016x<27+80
3 Simplify 27+8027+80 to 107107.
16x<10716x<107
4 Divide both sides by 1616.
x<\frac{107}{16}x<
16
107
Done
