The expression 6x^2 will have the shape of a parabola when graphed
<h3>What are quadratic equations?</h3>
Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
<h3>How to determine the shape of 6x^2 when it is graphed?</h3>
The function expression is given as:
6x^2
Express the function as an equation.
So, we have
y = 6x^2
The above equation is a parabola or a quadratic equation.
All quadratic equations have the same shape and the shape is parabola
This means that the expression 6x^2 will have the shape of a parabola when graphed
Hence, the expression 6x^2 will have the shape of a parabola when graphed

The percentage increase of the value of Tessa's stock is 22%
Step-by-step explanation:
The percentage of increase = 
× 100%, where:
- New: is the value after increasing
- Old: is the value before increasing
Tessa bought stock in a restaurant for $278.00.
Her stock is now worth $339.16
We need to find the percentage of increase of the value of
Tessa's stock
∵ The initial value of the stock = $278.00
∴ The value of the stock after increasing = $339.16
- Substitute these values in the rule above
∴ The percentage of increasing = 
× 100%
∴ The percentage of increasing = 0.22 × 100%
∴ The percentage of increasing = 22%
The percentage increase of the value of Tessa's stock is 22%

1.
d=number of dudes
l=number of ladies
total is 55 so
d+l=55
total cost is 75 so
2d+l=75
multiply first eeuqaiton by -1 and add to second
2d+l=75
<u>-d-l=-55 +</u>
d+0=20
d=20
sub
d+l=55
20+l=55
l=35

around the edge
means perimiter
disregard how deep the pool is
60 feet long
x wide
P=2(L+W)
P=220
220=2(60+x)
divide 2
110=60+x
minus 60 both sides
50=x
it has to be 50 feet wide
