-10 = -10 + 7m
Add 10 to each side: 0 = 7m
Divide each side by 7 : 0 = m
Please take a second and just LOOK at the equation you started with.
It says:
-- You have this number '-10' .
-- Your number -10 is going to be exactly the same size
after you add 7 of something to it.
The ONLY way that could happen is if the 'something' is 'nothing' .
' m ' must be nothing.
Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box
----------------------------------------------------
----------------------------------------------------
The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x
Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter).
The height of the box is x inches due to this portion being folded up.
Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x
Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).
Answer:
f=4
Step-by-step explanation:
-11f=7(1-2f)+5
-11 f=7-14f+5
14f-11f=12
3f=12
f=4

Hello!
First you have to find the area of the bigger square
When it goes from the center to a corner you multiply the value by 2 to find one side
9 * 2 =18
Now you find the area
18 * 18 = 324
Now we find the area of the smaller region
4 * 2 = 8
Find the area
8 * 8 = 64
Now we subtract these
324 - 64 = 260
The answer is 260
Hope this helps!
