(x² + 16x)² = 17²
√x² + 16x)² = √17²
(x² + 16x) = (+-)17
1st equation: x²+16x-17 = 0
2nd equation:x²+16x+17 =0
Let's solve these 2 quadratic equation:
1st equation x' =1 & x" = - 17
2nd equation x'= (-8+√47) & x" =(-8-√47)

Answer:
- length: 4 m
- breadth: 3 m
- height: 1 m
Step-by-step explanation:
The product of ratio units is 12 unit³, so each must stand for 1 m.
The dimensions of the room match the ratio units:
4 m length by 3 m breadth by 1 m height
Answer: 22 small snow cones and 34 large snow cones were sold.
Step-by-step explanation:
Let x represent the number of small snow cones that were sold.
Let y represent the number of large snow cones that were sold.
Selena's snow cone stand sells small snow cones for $2 and large snow cones for $3.50. One summer day, she sold $163 worth of snow cones. This means that
2x + 3.5y = 163 - - - - - - - - - - 1
If the number of large snow cones sold was 12 more than the number of smalls snow cones, it means that
y = x + 12
Substituting y = x + 12 into equation 1, it becomes
2x + 3.5(x + 12) = 163
2x + 3.5x + 42 = 163
5.5x = 163 - 42
5.5x = 121
x = 121/.5 = 22
y = x + 12 = 22 + 12
y = 34
Answer:
1:94 2:-94
