Need someone to help me with my math work

The small triangle has a long leg of 8. The triangle area formula is used to derive this. Now, there can be a ration equation.

10/4 = x/8

x = 20

Now use the formula.

A=1/2bh

A=1/2(10*20)

A=100

Area of DEF is 100 m^2.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
