Answer:
x²-16
Step-by-step explanation:
x²-16 =0
Add 16 to both sides
x²-16 + 16 = 0 + 16
Simplify
x²= 16
For x²=(fa) the solutions are x = √(fa), -√(fa)
X=√16 ,X= -√16
√16=4
-√16 = -4
x=4, x= -4
Answer:
Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.
Step-by-step explanation:
Consider the provided information.
We need to write a real world situation that could be modeled by the equation 100-6x=160-10x.
You can use any situation to represents this equation.
The left side of the equation consists of a constant and a variable also the right side of the equation consists of a constant and a variable.
Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.

5 times 8 is 40
Answer:
-145
Step-by-step explanation:
-5-15-25-x=100
First, get all the numbers(including 100) on one side and x on the other side(make sure x is POSITIVE, not negative)
-5-15-25-100 = x
Two negatives = addition
-5 - 15 = -20
-25 - 100 = -125
Now add, 20 and 125, and keep the negative
-125 - 20 = -145
