Answer:

Total Surface Area = 2(LW+WH+LH)

Step-by-step explanation:

Surface Area of;

face 1 = LW

= 20 × 10

=200

face 2 = WH

= 10×12

= 120

face 3 = LH

= 20×12

=240

TSA = 2(200+120+240)

=560×2

=1120

Well, since it is multiple choice, you can just eliminate the answers. If you take 5/4 it equals 1.25. Then you go through the choices. All of the numbers, except 7.2 (C) are infinite. And, 7.2 gives you the 1.25 from before... which is your answer

Twice the difference of a number and 3 equals 2 use the variable c for the unknown number.

Lesechka [4]

The number is 4

Step-by-step explanation:

First of all we have to convert the given statement in mathematical form.

Let c be the number then according to given statement

$2(c-3) = 2$

We have to isolate the variable in the equation

Dividing both sides by 2

$\frac{2(c-3)}{2} = \frac{2}{2}\\c-3 = 1$

Adding 3 on both sides

$c-3+3 = 1+3\\c = 4$

Hence,

The number is 4

Substitute 1 in for x, -2 in for y, -3 in for z, and solve.

(1³)(-2)(-3²) + (1²)(-2²)(-3²) + (1)(-3)

-18 + 36 - 3
