Answer:
Hi, there your answer will be p=6
Step-by-step explanation:
Step 1: Add 5 to both sides.
4p−5+5=19+5
4p=24
Step 2: Divide both sides by 4.

p=6
Answer:
Undefined
Step-by-step explanation:
First, slope is change in y over change in x, or rise over run. Plugging these points in (y1-y2)/(x1-x2)=(2-8)/(-6--6), or -6/0. Oh no! You can't divide by 0. Therefore, the slope is undefined.
You can also see this by graphing the line, which is a straight vertical line. Vertical lines have undefined slopes.
You just need to plug those expressions inside the formula: it doesn't matter if they're expressions involving a variable instead of plain numbers: the formula becomes

If you want, you can simplify it by expanding the square and then multiply the two parenthesis:

Answer:
7X8
Step-by-step explanation:
There is 7 spaces along one side and 8 along the other, area=l x w (length multiplied by width)
Answer:
33.3333% decrease
Step-by-step explanation:
Percent change formula:
, where x is the new value and y is the starting value.
Plug in values and solve:

-33.3333% change, or a 33.3333% decrease.
