I don't actually know, im not smart, I'm just answering for the points
Answer:
You need to satisfy the equation.
I will solve one.
Step-by-step explanation:
x -2 < -5
now add + 2 to both sides to keep its value.
now we end up with x <-3, which means that the value of x should be less than -3 in order to satisfy the equation.
So -5 is an answer, -4 is an answer, but not -3 because it should be less than -3 not equal.
As for number 9 the dash underneath the less than symbol means that it can equal to.
Hope this helps.
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
Answer:
Obviously, it's 2
Step-by-step explanation:
First, 1 is 1x1, so branch out under both 1's and put 1 x 1. Then, you add 1 + 1 + 1 + 1, which is 4. Then you do 4 - 2 since it is the two 1's in the original problem, and you get 2.
This is SUPER extra...
As well as mathematically incorrect lol
