A hockey team is revealing their championship banner outside their stadium. The banner is in the shape of a triangle with

a height that is 4 times as tall as the base length of the banner. If the total area of the banner is 18 square meters (18 m²),

what is the length of the base of the banner in meters?

The area (A) of a triangle is A = I x base x height.

Answer : The length of the base of the banner is, 9 m

Step-by-step explanation :

Let the base length of the banner be, x

So, the height of the banner will be, 4x

Formula used :

Area of triangle =

Given:

Area of triangle = 18 m²

Area of triangle =

18 m² =

Length of the base of the banner = x = 9 m

Height of the banner = 4x = 4 × 9 = 36 m

Therefore, the length of the base of the banner is, 9 m

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
