Answer:
SA=276
Step-by-step explanation:
Formula for rec. prism= 2(lw)+2(hl)+2(hw)
220 = SA for the bottom rectangular prism
56 = SA for the top figure
220+56=276
SA=276cm
The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
