Find the missing value for X

Mathematics
1 answer:
castortr0y [4]3 years ago
7 0
If we assume that BC is bisecting AD, and that AE is half of AD, we can set up the equation:

2(19)=5x-7

Then we can solve directly for x:

38=5x-7
45=5x
x=9

So we have then calculated x which is equal to 9.

Which are equal to 3/2?
KIM [24]
Explanation:

Starting with the first option, the square root of 12 and 8 isn’t a perfect square so it definitely can’t be reduced to 3/2.

It is the same for the second option as well.

Third option :
Root of 36 is 6
Root of 16 is 4

6/4 = 3/2

Fourth option:
Root of 81 is 9
Root of 36 is 6

9/6 = 3/2

Answer:

Therefore, the third and fourth options are the correct choices.

Hope this helped!

A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
Volgvan
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).
