Step-by-step explanation:
-5 ≤ 1 - 2x < 9
Let's first break this down into two different inequalities.
1 - 2x ≥ -5
Subtract 1 from both sides.
-2x ≥ -6
Divide both sides by -2
x ≤ 3
Now, let's do the second inequality.
1 - 2x < 9
Subtract 1 from both sides.
-2x < 8
Divide both sides by -2
x > 4
let's combine each inequality to get our reduced compound inequality.
-4 < x ≤ 3
To plot this, put a hollow point at -4. A hollow point looks something like the letter o.
And put the second point at 3. This time, fill in the point so it looks whole.
Now, connect your points.
It should look something like this:
Answer:
Step-by-step explanation:
step 1
Find the length of the base L
we know that
The surface area of a rectangular prism is equal to
where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
substitute
we have
substitute in the formula and solve for L
step 2
Find the volume of the rectangular prism
The volume is equal to
we have
substitute
