Answer:

A. the difference of two squares

Step-by-step explanation:

we are given

$x^2-121$

we can write

$121=11\times 11$

$121=11^2$

so, we can see that

x^2 is square

11^2 is also square

so,

$x^2-11^2=square-square$

It means that

two squares are subtracted

so, it is difference of two squares

so,

A. the difference of two squares

What is the lateral area of a prism which has a lateral edge of 4 inches and has a regular pentagonal base with an edge of 12 in

Nat2105 [25]

Check the picture below.

so the pentagonal prism in the picture is been seen from the bottom, namely so we can see its base, however the base is at the bottom, what does that mean, it means that the pentagonal bases are the top and bottom of the prism, that matters, because the other sides are the lateral sides.

so, if we notice, the lateral sides are really just 5 rectangles, each one a 12x4, so if we simply get the area of all those rectangles.

5(12 * 4) = 240 in².
