7 + 2(x - 3) + 5x
= 7 + 2x - 6 + 5x <em>distributed 2 into x - 3</em>
= 7 - 6 + 2x + 5x <em>grouped like terms together</em>
= 1 + 7x
You didn't provide an image of the steps but hopefully you can figure it out based on the information I provided.
Answer:
d: 15 units squared
Step-by-step explanation:
The area of a triangle is 
:
- Base: 5
- Height: 6
- Area: (5•6)/2=30/2=15
The volume equals length x width x height so multiply all of those with a calculator and you’ll get your answer hope I helped :)
Add numbers with the same amount of variables
-x^2 + (-7x^2) = -8x^2
– 28x (+ 14x )= -14x
7 (+ 8) = 15
-18x² - 14x + 15 is your answer
hope this helps
Divide them
We'd get
2n^2+1/10n + 1
