HELP ME!!! 25 POINTS!!

Answer:

The total distance walked by Paulo is 3750 feet.

Step-by-step explanation:

Here the four points are<em> (-2,1) (-2,-7) (5,-7) (5,1)</em>

Moving from stop A to B, only the y coordinate changes,

the change is ,

=1-(-7) = 1+7 = 8 units

Moving from stop B to C, only the x coordinate changes,

the change is ,

=5-(-2) = 5+2 = 7 units

Moving from stop C to D, only the y coordinate changes,

the change is

=1-(-7) = 1+7 = 8 units

Moving from stop D to A, only the x coordinate changes,

the change is

=5-(-2) = 5+2 = 7 units

Thus, the total distance traveled is 8+7+8+7 = 30 units

It is given that <em>1 unit = 125 feet</em>

Thus, the total distance traveled is = (125)(30) = 3750 feet

The total distance walked by Paulo is 3750 feet.

Math help 30 points
mash [69]

Again here we're using like terms

a) -2x² + 12x² = 10x² (they have the same term that's why I grouped them together)

-4x + 2x = -2x

13 - 25 = -12

So the final answer is 10x² - 2x -12

b) 7x² - (-7x²) = 7x² + 7x² or 14x²

4x - (-3x) = 4x + 3x or 7x

-26 - 15 = -41

The final answer to this one is 14x² + 7x - 41
