Answer:
y = -2
Step-by-step explanation:
A. 15-35=-20
b. -2+7=5
c. -10+14=4
d. 60-100=-40
Answer:
Step-by-step explanation:
(x−a)(x−b)=x2−(a+b)x+ab
Now, this with the third bracket.
(x2−(a+b)x+ab)(x−c)=x3−(a+b+c)x2+(ac+bc+ab)x−abc
But there’s another way to do this, which is easier. Assume the given expression is equal to 0, then, we can form a cubic equation as
x3−(sum−of−roots)x2+(product−of−roots−taken−two−at−a−time)x−(product−of−roots) , which is essentially what we got above.
30 is the answer. You do 10X 3 which is 30- 2 which is 28 and 28 to the nearest 10th is 30
13/8 = 1 5/8
Since 13/8 = 1 5/8, A and B cannot be correct.
5/8 > 1/2
Since 5/8 > 1/2, 13/8 is closer to 2 than to 1. Therefore, the answer is D. closer to 2 than to 1.
