Atriangular poster has a base of 2 1/2 feet and a height of 1 3/4 feet what is the area of the poster

a=

Step-by-step explanation:

formulas:

a= b x h x

or           (both equations get the same answers)

a= b x h ÷ 2

imma stick with the second one kuz i usually use that one but ur preference.

so,

base(b) = =

height(h) = =

now fill it in to the equation:

a=b x h x                        a= b x h ÷ 2

a= x x                         a= x ÷ 2

a=                                   a= ÷ 2

a=                                   a= ÷ 2

                                          a=  

                                           a=

o well i did both lol

now you ca compare the two equations now  :]

plz give brainliesttttt

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
