Answer:
Step-by-step explanation:
case 1
cost of 20oz bottle of soda = $1.20
dividing both side by 20
cost of 20/20 oz bottle of soda = $1.20/20
cost of 1oz bottle of soda = $0.06
__________________________________________
Case 2
cost of 12oz bottle of soda = $0.85
dividing both side by 12
cost of 20/20 oz bottle of soda = $0.85/12
cost of 1oz bottle of soda = $0.07
Based on above calculation, we can see that first deal 20oz bottle of soda at costs $1.20 is better deal as per unit cost is $0.06 which is less than 12 oz can of soda costs $0.85 which is equivalent to $0.07 per unit cost
A triangle will be produced from the intersection of the vertical plane and pyramid. The correct options are triangles and trapezoid.
<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.
Given that a vertical plane passes through a pyramid that has a horizontal base. Therefore, when the vertical plane and the pyramid meets or intersect the two dimensional figure that will be produced when the two intersect is triangle. It can also be trapezoid if the vertical plane does not intersect exactly in mid of the pyramid.
Hence, a triangle or a trapezoid will be produced from the intersection of the vertical plane and pyramid.

Answer:
x is greater than or = to 8
Answer:
yes, ±2
Step-by-step explanation:
The x-intercepts are found by setting y=0 and solving for x:
x^2/4 = 1
x^2 = 4
x = ±√4
x = ±2
The x-values of interest are -2 and +2.
