We can make an equation out of this by defining this mystery number as x. We can also use the word "of", by realizing that the word means multiplication.
Therefore, we have:
2/5x -3
If we plug in 25, we get:
2/5(25) - 3 =
50/5 - 3 =
10 - 3 =
7
Hopefully this helps!
5.7 x 10⁸ = 570,000,000 Choice A.
Choice B. 57,000,000 would have been 5.7 x 10⁷
Choice C. 5,700,000,000 would have been 5.7 x 10⁹
Choice D. 5.70000000 would have been 5.7 x 10⁰
1a) 4:2 = 2
4.98 x 2 = $9.96
1b) 3:2 = 1 1/2
4.98 x 3/2 = $7.47
2a) 9:3 = 3
4.80 x 3 = $14.40
2b) 12:3 = 4
4.80 x 4 = $19.20
3a) 6:2 = 3
15.00 x 3 = $45.00
3b) 5:2 = 2 1/2
15.00 x 5/2 = $37.50
Polynomial of degree seven can have the maximum 7 real solutions,
so maximum number of x-intercepts is also 7.
Answer:
(a + 9)(a - 5)
Step-by-step explanation:
Given
a² + 4a - 45
Consider the factors of the constant term (- 45) which sum to give the coefficient of the a- term (+ 4)
The factors are + 9 and - 5 , since
9 × - 5 = - 45 and 9 - 5 = 4 , then
a² + 4a - 45 = (a + 9)(a - 5) ← in factored form
