Answer:
width = 8, length = 42
Step-by-step explanation:
Let x = width, then length = 4x+10.
A = l x w
336 = x(4x+10) put into standard form
4x2 + 10x - 336 = 0 divide by 2
2x2 + 5x - 168 = 0 and solve using the quadratic formula and get
-21/2 and 8, the neg answer will not work, so the width = 8, length = 42

Step-by-step explanation:
Answer:
Number of volleyballs bought = 8
Number of basketballs bought = 11
Step-by-step explanation:
Given that:
Total amount spent = $204.20
Let,
x be the number of volleyballs
y be the number of basketballs
According to given statement;
y = x+3 Eqn 1
8.20x+12.60y=204.20 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
8.20x + 12.60(x+3) = 204.20
8.20x + 12.60x + 37.80 = 204.20
20.80x = 204.20 - 37.80
20.80x = 166.40
Dividing both sides by 20.80
Putting x=8 in Eqn 1
y = 8+3 = 11
Hence,
Number of volleyballs bought = 8
Number of basketballs bought = 11
