Answer:
A) 14x + 2
Step-by-step explanation:
(2x + 2x) + (5x + 5x) + (1 + 1)
= 4x + 10x + 2
= 14x + 2
You can only add 4x and 10x since they both have a variable (x). You cannot add 2 since 2 doesn't have a variable, so the answer in simplest form is 14x + 2
2) Right angles always equal 90°
3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.
4) Removing the m and replacing with the congruent symbol.
I'm not too sure how this goes but it should be something like that.
