Answer:
x = 3
Step-by-step explanation:
First you want to divide both sides by 5 to get 2x-4 = 2.
Afterwards, you add 4 to both sides of the equation. 2x = 6
Divide both sides by 2. x = 3
For the above figure, the formula is,
x² = WY (YV + WY)
WY = 5
YV = 12
Substituting in the above formula,
x² = 5 x (12 + 5)
x² = 5 x 17 = 85
x² = 85
⇒ x = √85 = 9.21954 = 9.220
