Not much info. x=2, y= -1
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
<span>SA=178.08 yd^2
</span>V=141.12 yd^3
Lcm is found by finding the factors and making a mega group with all the factors of both groups, excluding repeats from different groups so
12=2 times 2 times 3
18=2 times 3 times 3
megagroup=2 times 2 times 3 times 3=4 times 9=36
the LCM=36
Let P = total pay by Keiko per year.
P = $320 + $1500 + $600
P = $2420
The inverse of the funtion <span> f(x) = 4x
</span><span> f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4

Looks like none of the answer you have given are correct.
