I'm not sure about my answer but I think it's perpendicular lines
-8x+5y= -40
First, add 8x to both sides
5y= 8x-40
Now divide both sides by 5
y= 8/5x-8
Answer:
the length is 18.4
Step-by-step explanation:
Because the denominator (bottom number) of the fraction tells you
how many equal pieces the whole thing has been cut up into.
When you cut up the whole thing into 6 pieces, each piece is bigger
than if you cut it into 8 pieces, but less than if you cut it into 3 pieces.
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
