Answer:

D) 2x² + x - 10

Step-by-step explanation:

First, distribute the negative sign to all terms within the second parenthesis:

- (4x - x² + 6) = -4x + x² - 6

Next, combine like terms:

5x + x² - 4 - 4x + x² - 6

(x² + x²) + (5x - 4x) + (-4 - 6)

2x² + x - 10

2x² + x - 10 , or D) is your answer.

X^{2} -25=0 Please help meeee

-BARSIC- [3]

Answer:

$x=5,x=-5$

Step-by-step explanation:

$x^2-25=0$

Add 25 to both sides:

$x^2-25+25=0+25$

$x^2=25$

Square root both sides:

$x=\sqrt{25},\:x=-\sqrt{25}$ (Since a negative number multiplied by itself gives positive, there are two answers.)

$x=5,x=-5$

Step-by-step explanation:

35% of 5 liters is 1.75 liters

1.75 liters + 8 liters = 9.75 liters (only juice)

(5 liters + 8 liters = 13 liters) (the whole thing)

So, 9.75/13 is 75%
