Answer:
C=10. They did distributive property. Hope this helped!
Step-by-step explanation:
Answer:
The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.
(The probability of getting heads on the toss of a coin is 0.5)
Step-by-step explanation:
The Product Rule is evident from the visual representation of all possible outcomes of tossing two coins.
Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)
Answer:
Almost Correct!
Step-by-step explanation:
The general form of the equation of a circle is: x2 + y2 + Dx + Ey + F = 0, where D, E, F are constants. No factor multiplies the terms x2 and y2.
we are given
to write the sets of points from -2 to 5 but excluding 2 and 5 as a union of intervals
so, first interval is
-2 to 2 by excluding 2
[-2,2)
Second interval is
2 to 5 by excluding 2 and 5
so, we can write as
(2,5)
now, we can find total interval
we get
[-2,2) ∪ (2,5)..............Answer
