Answer:

0.45

Step-by-step explanation:

This question is asking you to find the value of the equation when j = -4 and when k = -0.7. To do this, we must substitute j with -4 and k with -0.7:

(-4 * -0.7 - 1) / -4

= (2.8 - 1) / 4

= (1.8) / 4

= 0.45

Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw

so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2

split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so

bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

ANSWERS
SA=178.08 yd^2
V=141.12 yd^3
