Answer:
B) 72
Step-by-step explanation:
28+(17x+4)=4+24x
17x+32=24x+4
32=24x-17x+4
32=7x+4
7x=32-4
7x=28
x=28/7
x=4
WGH=17x+4=17(4)+4=68+4=72

Answer: $ 38.69 ; There are 12 people in the crew
Surface area of the prism is 2xy+2xz+2yz
I think, we can cut hole on the face of the prisma 40x30, and size of the whole will be 5X5X5
hole increases surface area. If side of the cube is "a", then a^2 is the area of the one face of the cube.
when we are doing the hole, we remove 2 faces and add 4 more faces, so
2xy+2xz+2yz-2a^2+4a^2= 2xy+2xz+2yz+2a^2
So, 2*5*40+2*5*30+2*40*30+2*5^2=3150 cm^2
i hope it helps, it is what i can come up with now

(The positives are greater than the negatives.)
(The smaller negative numbers are greater than the larger negative numbers.)
