Answer:
Multiply it by itself one time.
Step-by-step explanation:
For example, if you are trying to find 3 squared, you would do 3*3.
If it's 3 cubed, you do 3*3*3
And so on and so forth
Reflection across the x-axis, followed by a, ?
-3a+3a+6=7
0a=1
a=error. As a result, this equation has 0 solution. Hope it help!
Answer 20mm
Point H is even with point E and I is exactly half way in between E and F. EF = 40 half of that is 20. This also works with HG, BC, and JK.
HI and IJ are the same length so both are 20mm
