Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
40! When you add all four angles of a quadrilateral together, you will always end up with 360. So, 360-75-120-125=40 :) have a great day!
Answer: You should cut out squares that are 4 inches by 4 inches.
One of the ways to do this problem is write and graph an equation. We can write an equation for the volume of this shape and then use a graphing calculator to graph it. If we look where the graph crosses 440, we will have our solution.
The volume needs to be 440. If we let x equal the side of the square that is cut out, we have the following dimensions.
Length = 19 - 2x
Width = 18 - 2x
Height = x
Volume = LWH
So our equation could be: y = (19 - 2x)(18 - 2x)x
If you graph that equation, it will intersect at the point (4, 440). Therefore, our square could be 4 by 4 inches.
A) n x 2.0
b) n x 2.0 = y
Hope this helps :)
Answer:
A
Step-by-step explanation:
A -8/5 = -1.6 which is less than 0.625 because 0.625 is closer to zero
