Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
Answer:
f
Step-by-step explanation:
the box plot is divided into quarters, the line on the end to 20 being 1/4th, the start of the box to the line in the box being another 1/4th, the middle line to the end of the box is another 1/4th, and the last line is the last 1/4th
Answer:
√100
Step-by-step explanation:
Given the following numbers: √220, -10, √100, 11.5,
Let's arrange the numbers from the largest to the smallest (in descending order).
Note: √220 ≈ 14.8
√100 = 10
From the largest to the smallest number, we have: √220, 11.5, √100, -10
Therefore, the number in the third position is √100
Solution:
Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.
The number zero has infinite factors.
The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.
Prime integers has only two factors one and itself.
Non prime integers has more than two factors.
But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.
So, yes Kia is not absolutely true, but if she has written the statement in this form: Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.
The Answer is (x-9) (x-3) Factor 12 and 27 out.
