Expanded form means making a number into an equation that makes your number the sum. It is a way to represent the value of each digit in a number.
One possible answer could be:
12,000,000 + 400,000 + 30,000 + 90
= 12,430,090
Answer:
D
Step-by-step explanation:
Any ellipse has the following equ
ation:
where
- 2b = vertical axis length
- 2a = horizontal axis length
(as in the picture)
So it should be like:
Since it should be moved to the right and up, the answer would be:
Answer:
A
Step-by-step explanation:
Given
x² - 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, thus
(x - 7)(x + 2) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 2 = 0 ⇒ x = - 2
