PLEASE HELP

1) A triangle has two sides of length 3m-4 and one side of length m. if the total perimeter is 76 inches, how long is side m?

2) A square has 4 sides of length 4x+5 if the total perimeter of 200 find the value of x

The parabola opens: y=√x-4 (principal square root) up down right left

For each proportion find the unknown number x 1/5/8=×/15

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5
