If the length of each side of an equilateral triangle were increased by 50 percent, what would be the percent increase in the area?

The area increase by 225%

Step-by-step explanation:

attachment of a triangle

The area of a triangle equilateral is calculated with the next formula:

A=

=

= *3

h=

h=

replacing in the A equation:

A=

A=

Now each side increse by 50% ⇒ a=1.5a

A=

A=

A=2.25 *

It means that the area incrase by 225%

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
