A) Action: multiply both sides by 4.
Have a look:
(x/4)x4=16x4
x=64
As you can see, the value of x can be found by multiplying 4 on both sides.
Hope I helped :)
Right isosceles, which has two sides the same length and one angle that measures 90 degrees.
Can you be more specific? I need a question and I need a close up ! Lol but I’m trying to help.
