-b[a + (c-d)^2]
-(-8)[3/4 + (-2 -3)^2]
8 [3/4 + (-5)^2]
8 [3/4 + 25]
8 [25.75]
206
x= 2
hope it's helpful ❤❤❤

answer:
61.712
60 feet = 18.288
left wire = 80-18.288 = 61.712
see below
3^-7 x 3^7 = 1
The negative exponents put it in the denominator
1/ 3*3*3*3*3*3*3 * (3*3*3*3*3*3*3) = 1
The 3's cancel leaving
1/1 = 1
1=1
