<em>2</em><em>5</em><em>x</em><em>-</em><em>4</em>
Step-by-step explanation:
3x+10x
+ 2x. -4
=5x+10x-4
=15x-4
60 because 15x8 is 120 and the total degrees of a triangle is 180. 180-120 is 60.
4/5x=7/5 you have to divide 7/5 by 4/5 which equals to 1.75/5 which is equal to x
Yes it is. "To the power of" just means you are multiply a number by itself how many times.
