She would have saved 30 dollars.
Pythagorean theorem
c2 = a2 + b2
71^2 = 43^2 + b2
5041 = 1849 + b2
3192 = b2
b = 56.5 which is answer choice d
Equation 1 :
| 5x - 6 | = -41.....no solution because an absolute vlue cannot equal a negative number
equation 2 :
| 7x + 13 | = 27...2 solutions
C. equation 2 has more solutions then equation 1.
