Answer:
(45 - 25) / 2 × (2 + 3)
Step-by-step explanation:
Given:
45 - 25/2 × 2 + 3
By trials:
(45 - 25) / (2 × 2) + 3
= 20/4 + 3
= 20/7
Another trial:
(45 - 25)/2 × (2 + 3)
= 20/2 × 5
= 20/10
= 2
The parentheses should be inserted like this
(45 - 25) / 2 × (2 + 3)
Set side lengths equal to each other and solve for x. All sides are equal lengths in a square.
6x - 1 = 4x + 6
2x = 7
X = 3.5
Plug in x in one of the equations
4 x 3.5 + 6 = 20
Each side is 20 cm
