Answer:

The total area that is painted yellow is 930\ in^{2}

Step-by-step explanation:

we know that

The area of the outside of the box is equal to the surface area of the box minus the area of the top

The area of the outside is

A=B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the box

<em>Find the area of the base B</em>

B=(18)(15)=270\ in^{2}

<em>Find the perimeter of the base P</em>

P=2(18+15)=66\ in

we have

H=10\ in

substitute the values

A=270+(66)10=930\ in^{2}

Alex buys 5 DVDs. Each DVD costs $9. If Alex receives a $2 discount on each DVD, what is the total amount of money alex apends?
LekaFEV [45]

Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.

Factor completely 5ab(x 6) − 4(x 6). Prime (x 6)(5ab 4) (x 6)(ab) (x 6)(5ab − 4).
kaheart [24]

The complete factor of the polynomial 5ab(x + 6) − 4(x + 6) is (x + 6)(5abx − 4). Then the correct option is D.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 5ab(x + 6) − 4(x + 6).

Take (x + 6) common, then we have

5ab(x + 6) − 4(x + 6)

(x + 6)(5abx − 4)

The complete factor of the polynomial 5ab(x + 6) − 4(x + 6) is (x + 6)(5abx − 4). Then the correct option is D.

More about the polynomial link is given below.

Elena's diagram for 372 has 7 tens. The one for 372 : 3 has only 6 tens. Why? Where
Andru [333]

Answer:

  one ten was traded for ten ones

Step-by-step explanation:

372 cannot be divided by 3 easily. However, 360 +12 can be divided by 3 easily, so it makes sense to trade one of the seven tens for ten ones. That will leave 6 tens, but give twelve ones.

  370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones
