Answer:

$5x-2x$

Step-by-step explanation:

Let's call that number $x$ .

when we are asked for a difference we must substract quantities.

In this case we need the difference between five times a number (the number is represented by $x$ ) and twice that number:

five times the number x is equal to

$x+x+x+x+x=5x$

twice that number x is equal to:

$x+x=2x$

thus, the difference is: $5x-2x$

Which function is odd?

ddd [48]

The function is odd if you can replace every x with -x and get the oposite equation
example
if you replace x with -x in y=x^3, then you get -x^3, so therefor the functin is odd

so

replace x with -x

a. we get x^3+4, nope
b. we get -2x^3, yep
c. we get x^4-9, nope
d. we get x^4-4x, nope

answer is B

Your client has saved $1,860 for a down payment on a house. A government loan program requires a down payment equal to 3% of the

Delicious77 [7]

If there is a $5,000 deposit, that means the amount to be mortgaged is $82,500. Calculating 3% of that amount:

0.03 * $82500 = $2475

The closing costs of the loan are $2,475. When they close the deal, they must bring that PLUS the down payment to the table, or $7,475.

(B)

If they are putting 30% down:

0.30 * $310000 = $93000

Add that to all of the other costs listed, they'll need to bring $94,165.

(C)

Discarding the $25,000, the Paltrows are asking for a $100,000 mortgage loan. 2% of that is $2,000, and so the total mortgage is for $102,000.

(D)

I can't answer this because I don't know how the interest is charged

The area of the circular base of a cylinder is 36 square units. The height is 2

olya-2409 [2.1K]

Answer:

24 π

Step-by-step explanation:

First step is to determine the radius of the base. We have the area, so we can easily determine the radius. The base is a circle, and the area of a circle is given by A = π * r² , so r² = A / π

r² = (36 π) / π = 36

So, r = 6

The lateral surface of a cylinder is given by the following:

L = 2* π * r * 2

Now that we have r, we can easily calculate it:

L = 2 * π * 6 * 2 = 24π, second choice listed
