I dont know anything about these set of drivers
57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
Answer:
Andre has the correct answer. When simplified his answer is equivalent to the original equation.
x - shortest side
2x - second side
x + 26 - third side
174 ft - perimeter
x + 2x + (x + 26) = 174
4x + 26 = 174 |-26
4x = 148 |:4
x = 37 ft
2x = 2(37) = 74 ft
x + 26 = 37 + 26 = 63 ft
Answer: 37 ft, 74 ft and 63 ft.
