What is the surface area of the rectangular prism below?
Andrew [12]

Answer:

B ( 432 units^2)

Step-by-step explanation:

Total surface area= 2*(6*6)+ 4*(15*6)

There are 2 squares at each end of the same size so total area will be 2*(6*6)

If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)

In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2

Troy signed up for a new cell phone plan which charges him a fee of $40 per month, plus $0.05 for each text message that he send
nataly862011 [7]
He can send 600 messages.
40+0.05x=70
-40+0.05x=70-40
0.05x=30
So divide 30 by 0.05
and you get 600.

-4y>2x+4 What is the slope of this
vovikov84 [41]
Answer: -1/2

Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4

In y = mx + b; m is the slope

In this case, -1/2 is the slope
