One pair is 4.345+4.345 (which is the pair that does not involve grouping)
Answer:
31.1
Step-by-step explanation:
This is an isosceles triangle. Let us name the unnamed side y. y will also equal 22. We also know that this is a right triangle so using the pythagorean theorem we can calculate x. x = √(22^2+22^2) so x = 31.1.
Answer:
12x + 4x + 20
