21 plants are in the garden
Step-by-step explanation:
here , base = 7 m
height = 24 m
Thus , The area of the triangle (garden ) is 84 m ²

Answer:
1) matched samples
2) single sample
3) independent samples
Step-by-step explanation:
1) couples were taken and their behaviors matched
2) only one sample was used
3) two different samples were used and their average compared.
-2x=15-7y
x=-7.5+3.5y
-3x-8y=4
-3(7.5+3.5y)-8y=4
-22.5-10.5y-8y=4
-22.5-18.5y=4
-18.5y=4+22.5
-18.5y=26.5
y=-53/35
the fraction might not be in lowest terms.
The square of 4 and 2 adds up to 20!
4 square is 16.
2 square is 4
So 16+4=20
