Answer:
9>x>-3
Step-by-step explanation:
1) first lets write 2 inequalities:
9>x and -3<x
remember -3 is less than x is the same as x is greater than -3
so I can write -3<x as
x>-3
so 9 is greater than "x" and "x" is greater than -3.....Is there any way we can combine these inequalities?
fortunately, there is a way! combing 2 inequalities as one is called a compound inequality
so 9 is greater than x:
9>x
and x is greater than -3
9>x>-3
boom!
Hope this helps!
(to solve the inequality just take the compound inequality as two seperate inequalities)
First divide both sides of the inequality by 3.
On the left, the 3's cancel and you're left with j
and on the right, 6 divided by 3 is 2.
So we have j >2 which is the solution to this inequality.
I have graphed the inequality for you below.
Start with an open dot on 2.
We use an open dot because j > 2 but it is not equal to 2.
Then draw an arrow to the left to
represent all numbers greater than 2.
Hello from MrBillDoesMath!
Answer:
72
Discussion:
Total Surface area = area of pyramid base + 4 ( area of triangular face)
In our case this becomes
4*4 + 4( (1/2) (4)(7) ) =
= 16 + (2)(4)(7)
= 16 + 56
= 72
which is the first choice.
Note: the area of a triangular face was computed using (1/2) b h, which in our case is
(1/2) (4) (7)
Thank you,
