Find area of each of the faces.
4 triangle faces: 1/2 x b x h
1/2 x 8 x 10 = 40
40 x 4 (because there are four of them) = 160
one square bottom:
s^2
8^2 = 64
160 + 64 = 224
Collect like terms
15 + 3 + 9x + 7x = y
18 + 16x = y
Recall
b + mx = y
m = 16
b = 18
Answer:
3.636 hour. dividing 200miles /55m/h =3.636h
I'm sorry I really don't know I'm not really good with math that's why I got them brainly for other people's help because I really not that cool math and I'm homeschooled
Can’t see the picture clearly
