need answer quick!

Area of triangle = 14 unit²

Step-by-step explanation:

Given three points as shown in plotted graph

E ( -5 , 2)

F (2 , 2)

D ( -1 , -2)

Now area of triangle with three points can be calculated as

Area of Δ = [x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)]

Area of Δ = [ -5 (2+ 2) + 2(-2- 2)  -1(2 - 2)]

Area of Δ = [ -5 (4) + 2(-4)  -1(0)]

Area of Δ = ( - 28)

So , Area of Δ = 14 units²

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
