Kat is painting the edge of a triangular stage prop with reflective orange paint. the lengths of the edges of the triangle are (3x-4) feet, (x2 - 1) feet, and (2x2 -15) feet. what is the perimeter of a triangle if x equals four

First, let's convert X into 4

(3*4 - 4)ft,  (4*2 - 1)ft, (2*4*2 - 15)ft

Now lets simplify this a little

(12 - 4)ft, (8 - 1)ft, (16 - 15)ft

Awesome now lets finish up

8 x 9 x 1   /  2 = 36

The answer should be 36ft. Unless I did my math wrong.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
