Answer:
+ 16
Step-by-step explanation:
x² - 8x = - 10
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + (- 4) = - 10 + (- 4)²
x² - 8x + 16 = - 10 + 16
thus 16 is added to both sides to complete the square
This is a one-step equation. All you need to do is multiply the 2.5 over to the 20 to get x by itself.
x=50
Hope this helps!
The answer is infinitely many solutions.
If you graph them both are a straight line which means they are infinite
Answer:
5x5 = 25
5x0,5 = 2.5
5x0,03 = 0.15
Adding them makes: 25+2.5+0.15 = 27.75
