What is the surface area and what do I need to do?

kari74 [83]

check the picture below, that's pretty much the same block, or "rectangular prism", with a width of 10, length of 5 and height of 1.

so anyhow, is really 6 rectangles stacked up to each other at the edges, so, we can simply get the area of each of those rectangles, add them up and that's the surface area.

front and back, two rectangles of 5x1

left and right, two rectangles of 1x10

top and bottom, two rectangles of 10x5

$\bf \stackrel{\textit{front and back}}{2(5\cdot 1)}+\stackrel{\textit{left and right}}{2(1\cdot 10)}+\stackrel{\textit{top and bottom}}{2(10\cdot 5)}$

I'm not sure how to simplify this expression with the exponents rules of multiplication

Vedmedyk [2.9K]

The rule of exponential multiplication is (a^x)*(a^y)=a^(x+y)
using this with your expression, we can do
(10^1)*(10^3)*(10^2)=10^(1+3+2)=10^6
Final answer:
10^6 or 1 million

Let f(x)=x-2 and g(x)=x2-7x-9 fins f(g(-1))

vlabodo [156]

The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.
