Answer:
10m
Step-by-step explanation:
Use the area of triangle:
Area of triangle =
![\frac{1}{2} \times base \: \times height](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%20%5Ctimes%20base%20%5C%3A%20%20%5Ctimes%20height)
1/2 × b × 3 = 15
b × 3 = 30
b = 30/3
b = 10
Answer:
Nope they are not parallel.
Step-by-step explanation:
first find the slope of each equation.
-4x+4y= -1
4y= 4x -1
y= (4x-1)/4
y=x - 1/4
the other equation
4x +4y = -1
4y= -4x -1
y= (-4x-1)/4
y= -x -1/4
the slope is the number in front of the x so for the first equation, it is 1 and the second equation it is -1. Since they are not the same, they are not parallel but instead is perpendicular. TBH, just stop here as this is more than enough.
