Answer:

Step-by-step explanation:

area = 30x + 30(x+3) + 30(2x)

= 30x + 30x+90 + 60x

= (120x + 90) m²

length of planting area = x + (x+3) + 2x = 4x+3 m

area = 30(4x+3) = (120x + 90) m²

x = 5

maple area = 30(5+3) = 240 m²

locust area = 30(2·5) = = 300 m²

Answer:

Slope = 2 6/11

Step-by-step explanation:

<u>Formula:</u> \frac{y2}{x2}  -  \frac{y1}{x1}  = m

m = slope.

<u>Substitute the given points into the formula:</u>

\frac{35}{16}  -  \frac{7}{5}  = m

<u>Solve:</u>

\frac{35}{16}  -  \frac{7}{5}  =  \frac{28}{11}  = 2 \frac{6}{11}
