What is the area of triangle below?

24

Step-by-step explanation:

1. look at the graph window, the y axis goes up by 1 (2, 3, 4, 5, etc), and my answer assume the x axis is the same (it is not pictured)

2. split the triangle into two. the separated spot can be at x=3 because it forms two right triangles (right triangles have 90 degrees)

3. triangle dimensions: the first one is 2 by 4. to find the area of a rectangle, you multiply the length by width and divide by 2. 2 x 4 = 8, 8 divided by 2 is 4.

4. the second triangle is 4 by 5. 4 x 5 = 20, 20 divided by 2 is 10.

(you divide by 2 because two right triangles can make a square)

5. add the area of the two triangles, 20 plus 4 is . . .

24!

we have our answer :)

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

160 cm

step-by-step explanation:

you have to add all the sides together
