Answer:
2,121, 3,625, 6,540, 8,750
Step-by-step explanation:
2/5 x 4 = 1.6 since there are four kids and each kid soent 2/5 hours studying
In this equation, p=27 because it is the last term and q=3 because it is the coefficient of the first term. First find all divisors of these numbers:
27: 1, 3, 9, 27
3:1, 3
Then use +/- p/q to find all possible combinations
+/-1, +/-3, +/-9, +/-27, +/- 1/3
Or your answer can be written as: 1, -1, 3, -3, 9, -9, 27,-27, 1/3, -1/3
Hope this helps!
Answer:
(4x - 5)(x + 2).
Step-by-step explanation:
4x^2 + 3x - 10
4 * 10 = -40
We need 2 numbers whose product is -40 and whose sum is +3.
Theses are = - 5 and + 8.
So we write:
4x^2 + 8x + -5x - 10
= 4x(x + 2) - 5(x + 2)
= (4x - 5)(x + 2).
