Using the Distributive Property
The answer would be 3.
2 *4x = 8x and 2 * 3 = 6, to get 8x 6
Answer:
(x - 3)(x + 7)
Step-by-step explanation:
x^2 + 4x - 21
=> x^2 + 7x - 3x - 21
=> x(x + 7) -3(x + 7)
=> (x + 7)(x - 3)
You have:
x: the number of reams of white paper purchased
y:the number of reams of blue paper purchased
Then, you have the following system of equations:
x+y=10
3.50x+3.75y=36
When you solve the system shown above, you obtain:
x=6
y=4
The answer is: 6 reams of white paper
