Answer:
-2x² - 8x + 15 = 0
Step-by-step explanation:
Given the following algebraic expression;
x² – 7x + 5
-3x² - x + 10
To add the equation together;
x² – 7x + 5 + (-3x² - x + 10) = 0
x² – 7x + 5 - 3x² - x + 10 = 0
Collecting like terms, we have;
(x² - 3x²) - (7x + x) + (5 + 10) = 0
3/5
It should look like this...
x=3/5
(5*(3/5))=3
5*3 = 15
15/5=3
12.24 inches
you would do 10.2 x 1.2
hope this helps (look in the picture)
6041.666.....
We have: 725 : 12% = 6041.6666.....
