please help me find total surface area

Answer:

[tex]\frac{24}{a}[/tex] - b

[tex]\frac{b-2}{a}[/tex]

[tex]\frac{21}{a}[/tex]-[tex]\frac{b}{4}[/tex]

b - [tex]\frac{2}{3}[/tex]a

25 - 2b

5b - 10a

Step-by-step explanation:

a = 3 and b = 8

Plug in a and b into your equations.

25 - 2(8) = 25 - 16..........9

[tex]\frac{8-2}{3}[/tex] = [tex]\frac{6}{3}[/tex]..........2

5(8) - 10(3) = 40 - 30..........10

[tex]\frac{24}{3}[/tex] - 8 = 8 - 8..........0

[tex]\frac{21}{3}[/tex] - [tex]\frac{8}{4}[/tex] = 7 - 2..........5

8 - [tex]\frac{2}{3}[/tex](3) = 8 - 2..........6

Then you order least to greatest.

Answer:

y-0 = 4/5(x-2)

Explanation:

0 is the y point so it goes in the y-y1 spot. The m or the slope goes into the m spot by the parenthesis. The 2 goes into the spot of the m-m1. One thing that is important is that when plugging in the point into the equation is to always put in the inverse. So if 3 was the y point, the equation would be y-3, if it was a negative point it would be, y + 3.

Answer:

8x^2-22x+15

Step-by-step explanation:

Multiply them together

Answer:

There are many, many, different expressions equivalent, but if you distribute them together you come up with:

8x² - 22x + 15

Step-by-step explanation:

When distributing (4x–5) (2x-3) we should end up with four values, and then add them together.

[] The outside numbers of 4x and -3

-> 4x * -3 = -12x

[] The inside numbers of -5 and 2x

-> -5 * 2x = -10x

[] The left numbers of 4x and 2x

-> 4x * 2x = 8x²

[] The right numbers of -5 and -3

-> -5 * -3 = 15

Now we can add them together;

-12x + -10x + 8x² + 15

8x² - 22x + 15

Answer:

50,646

Step-by-step explanation:

Jim would have saved 50,646 in 4 years

1 Year= 12.6615

12.6615 x 4=50,646

Jim will have $5,149,010 in 4 years.

Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.

We have,

P = $84,410.

R= 15%

T = 4 years

Using Simple Interest

SI = (P x R x T) / 100

SI = (84410 x 15 x 4)/100

SI = 5,064,000

So, the amount is

= 84,410 + 5,064,000

= 5,149,010

Answer:

Step-by-step explanation:

To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.

a^2 + b^2 = c^2

c is the hypotenuse, the longest side of a right triangle.

a and b are the legs of the right triangle.

a = 7

b = 15

c = 17

7^2 + 15^2 = 17^2 ?

49 + 225 = 289 ?

274 ≠ 289

Thus, this triangle is not a right triangle since it does not satisfy the Pythagorean Theorem.

Answer:

Step-by-step explanation:

The two relations can be written in general form using the given variable definitions as ...

  5x +7y -57.40 = 0

  4x +2y -32.60 = 0

The solution using the cross-multiplication method is ...

  d1 = (5)(2) -(4)(7) = 10 -28 = -18

  d2 = (7)(-32.60) -(2)(-57.40) = -228.20 +114.80 = -113.40

  d3 = (-57.40)(4) -(-32.60)(5) = -229.60 +163 = -66.60

  x = d2/d1 = -113.40/-18 = 6.30

  y = d3/d1 = -66.60/-18 = 3.70

The cost of 1 sandwich is $6.30.

The cost of 1 burrito is $3.70.
