The solutions of the equation are -12 and 16
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then
∵ 2Ix - 2I - 8 = 20
- At first add 8 to both sides
∴ 2Ix - 2I = 28
- Then divide both sides by 2
∴ Ix - 2I = 14
Now By using the notes above equate x - 2 by 14 and -14
∵ x - 2 = 14
- Add 2 to both sides
∴ x = 16
∵ x - 2 = -14
- Add 2 to both sides
∴ x = -12
The solutions of the equation are -12 and 16

Answer:
Step-by-step explanation:
Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.
If you are trying to find the length of the sides of the squares, the formula is
Area = side^2
3025 = side^2
Take the square root of both sides.
sqrt(3025) = sqrt(side^2)
To find the square root of 3025, do the following
Press √
type in 3025
type in =
You should get 55.
======================
The second square is done the same way
√

=
And you should get 9.526
