Answer:

2 sqrt(15) + 3 sqrt(10)

Step-by-step explanation:

sqrt(6) * ( sqrt(10)+ sqrt(15))

Distribute

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(6) sqrt(10)+ sqrt(6) sqrt(15))

sqrt(60) + sqrt( 90)

sqrt( 4*15) + sqrt(9*10)

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(4) sqrt(15) + sqrt(9) sqrt(10)

2 sqrt(15) + 3 sqrt(10)

Answer:

≈ 15.5085

Step-by-step explanation:

√6 ≈ 2.45

6 is not a perfect square so its square root is irrational, therefore the decimal form can only be estimated.

√10 ≈ 3.16

The square root of 10 is a single number. That number is irrational, which means that its decimal expansion goes on forever without repeating, and cannot be expressed as a fraction.

√15 ≈ 3.17

This is not simplifiable. But this is approximately what equalled.

2.45(3.16 + 3.17)

= 15.5085

Multiply and simplify the product. (3 – 5i)(–2 + 4i) Select the product.

garri49 [273]

Answer:

-20i^2 + 22i - 6

Step-by-step explanation:

(3 - 5i)(-2 + 4i) = -6 + 10i + 12i - 20i^2 = -20i^2 + 22i - 6

if you want to go further,

-20i^2 + 22i - 6 = -2(10i^2 - 11i + 3)

A photo lab usually charges 1.45 per print to make a color print from a color transparency. During a special promotion, the char

Fiesta28 [93]

Answer:

$\large \boxed{\math{\$24.05; < 9}}$

Step-by-step explanation:

Let n = the number of prints

and C = the total cost.

At the regular price, the formula is

C = 1.45n

During the promotion, you must pay for the first nine prints: 9 × 1.45 = 13.05.

For anything over nine prints (n - 9), you must pay $13.05 plus the promotional cost of $1.10 for each print. The promotional formula is

C = 13.05 + 1.10(n - 9) {n > 9}

1. Calculate the cost of 19 prints

$\begin{array}{rcl}C & = & 13.05 + 1.10(19 - 9)\\ & = & 13.05 + 1.10 \times 10\\ & = & 13.05 + 11.00\\ & = &24.05\\\end{array}\\\text{The cost of 19 prints is $\large \boxed{\mathbf{\$24.05}}$}$

2. What number of the prints is a waste of money?

During the promotion, buying fewer than nine prints would be a waste of money, because you would not be taking advantage of the promotional savings.

Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of

djyliett [7]

Answer:

you get ten percent off but you didn't give the cost of the game

Step-by-step explanation:

The tax subtracts from the percent off, so 18%off - 8% sales tax =10% off

-18x-(-8y)=10 I think??? It's in standard form...
