You have to add up all the sides of the box
That's easy, here let me show you a example:
Identity property!
Because the identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." In this case, 0 is being added to 40.
Answer:
-5/3
Step-by-step explanation:
To solve this just plug in 7 wherever you see an x
we have
3/(7+2)-sqrt(7-3)
3/9-sqrt(4)
.3333-2= -5/3
Answer:
x = 4
Step-by-step explanation:
Solve the inequality
2x - 3 > 11 - 5x ( add 5x to both sides )
7x - 3 > 11 ( add 3 to both sides )
7x > 14 ( divide both sides by 7 )
x > 2
The only value of x greater than 2 is 4, thus
x = 4 is in the solution set
