Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2

Answer:
Integers are the set of whole numbers and their opposites. Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign. an example with numbers is 17positive and 17 negative both are 17 (clicks/jumps/etcetera) away from 0. There is no 0 positive or negative.
Answer:
1/2 L
Step-by-step explanation:
She makes 1 1/2 L of lemonade i.e. 3/2 L of lemonade.
She pours 1/4 of liter of lemonade into a thermos to take to the park. The amount of lemonade left is:
3/2 - 1/4 = 1 1/4 L = 5/4 L
Her brother drinks 2/5 of the remaining lemonade. The amount of lemonade that her brother drinks is:
2/5 * 5/4 = 1/2 L
Her brother drinks 1/2 L.
