Answer:
the number of pencils she bought
Step-by-step explanation:
p is just another variable like x or y
Answer:
20
Step-by-step explanation:
We can set up a percentage proportion to find the value of x.
Now we cross multiply:

The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:
Simplified:
To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
M=0-5/1-0
m=-5/1=-5
y-y1=m*(x-x1)
y-5=-5(x-0)
y-5=-5x
y=-5x+5
You had the right idea using the Pythagorean theorem to solve for b.
Problem is for that triangle to work, the 5 and the 2√2 would have to switch places. The length of a leg cannot be larger than the length of the hypotenuse for it to truly be a right triangle.
Pythagorean theorem only works for the right triangles. Only way to "solve this problem would be to bring in complex numbers.
5² + b² = (2√2)²
25 + b² = 2²(√2)²
25 + b² = 4(2)
25 + b² = 8
b² = 8 - 25
b² = - 17
b = √-17
b= (√17i)
Then the problem with THIS is a measurement/distance cannot be negative... which goes against exactly what that complex number i is.
