Let
x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m
Answer:
12
Step-by-step explanation:
we would do 475 divided among 40
475/40=11.875
but we would not use 11.875 so let's make it 12$
Answer:
2.7 litres of solution
Step-by-step explanation:
X1 = -1
y1 = 4
point-slope form is y - 4 = 2(x+1)
Plug 50 into y and find x.
5x + 10 (50) = 800
5x + 500 = 800
5x = 800 - 500
5x = 300
x = 300 ÷ 5
x = 60
