Answer:
decimal form 1.9 mixed number is 1 9/10
Step-by-step explanation:
Answer:
3/4=0.75
4/5=0.8
7/10=0.7
0.75+0.8=1.55
1.55-0.7=0.85
Step-by-step explanation:
Let the width be x.
Width = x
Length = 4x + 7
The area is 650 m²
x(4x + 7) = 650
4x² + 7x - 650 = 0
Using quadratic formula:

a = 4, b = 7, c = -650


Width = 11.9m
Length = 4(11.9) + 7 = 54.6m
Answer: Length = 54.6m and width = 11.9m
