What language are you programming in? Whatever print function you have it should probably go something like this.
The volume = 343
The surface area = 294

To calculate this in code you could just use
print(343-294);

Or you can use this
(You can swap out the 7s for the variable length)

Print((7*7*7)-(7*7*6));

Answer:

Step-by-step explanation:

Cube 7 to get the volume.(343)

Do 7^2 to get 49, then multiply by 6 to get the surface area(294)

Then subtract 343-294=49

First question:

1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)

Second question:

1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number

You want to carpet a 15 foot by 20 foot room. You have two carpet options to choose from. One is $1.50 per square foot and the o

Sauron [17]

Answer:

the answer is A because the cost of the more expensive one is 15+20=35 multiplied by 3 which will give me =$105

And the cheaper one is 15+20=35 multiplied by 1.50 = which is 52.5

so the amount more of the choice for the more expensive one is 105-52.5=52.5.

the answer is 52.50.

The height of a trapezoid is 6 in. and it’s area is 72 in to the 2nd power. One base of the trapezoid is 6 inches longer than th

Vitek1552 [10]

Given:

The height of the given trapezoid = 6 in

The area of the trapezoid = 72 in²

Also given, one base of the trapezoid is 6 inches longer than the other base

To find the lengths of the bases.

Formula

The area of the trapezoid is

$A=\frac{1}{2} (b_{1} +b_{2} )h$

where, h be the height of the trapezoid

$b_{1}$ be the shorter base

$b_{2}$ be the longer base

As per the given problem,

$b_{2}=b_{1} +6$

Now,

Putting, A=72, $b_{2}=b_{1}+6$ and h=6 we get,

$\frac{1}{2} (b_{1} +b_{1}+6)(6) = 72$

or, $b_{1}+b_{1}+6 = \frac{(72)(2)}{6}$

or, $2b_{1}+6 = 24$

or, $2b_{1}=24-6$

or, $b_{1}= \frac{18}{2}$

or, $b_{1}=9$

So,

The shorter base is 9 in and the other base is = (6+9) = 15 in

Hence,

One base is 9 inches for one of the bases and 15 inches for the other base.
