Answer:
5x-2x-x = 10 9z • 7p = 378
Step-by-step explanation:
With equations like these you're basically just plugging numbers in where there are variables. so if you have 5x-2x-x when x=5, you just plug in 5 wherever x is. 5x-2x-x turns into (5•5)-(2•5)-(1•5). you multiply the expressions in the parentheses to get 25-10-5 and then you simply subtract.
1. 5x-2x-x
2. (5•5)-(2•5)-(1•5)
3. 25-10-5
4. 10
We can do the same thing with your second example. 9z•7p when z=2 and p=3. When there is a z, you plug in a 2. When there is a p, you plug in a 3.
1. 9z•7p
2. (9•2) • (7•3)
3. 18 • 21
4. 378
hope this helps :)
Answer:
3
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor.
(2x + 5)(4x + 4)
= 2x(4x + 4) + 5(4x + 4) ← distribute both parenthesis
= 8x² + 8x + 20x + 20 ← collect like terms
= 8x² + 28x + 20 → A
