What is this i don't get it help me please

720ft²

Step-by-step explanation:

I'm guessing you have to find the area of the house.

Find the area of the rectangular portion of the house.

20 * 30 = 600

Find the area of the triangular portion of the house.

30 * 8 = 240

240 / 2 = 120

Add both together.

600 + 120 = 720

Best of Luck!

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.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
