Answer:

$\fbox{8x+36}$

Step-by-step explanation:

1. Use the distributive property to write the problem without parentheses. The distributive property says that you can multiply a number next to parentheses by all the numbers inside parentheses. The picture below explains.

$4(2x+9)=\\\\(4*2x)+(4*9)=\\\\4(2x+9)= 8x+36$

Therefore, your answer is

$\fbox{8x+36}$

12 is what percentage of 80

PIT_PIT [208]

Answer: " 15 % " .

_______________________________

→ " 12 is  15%  of 80 " .

_______________________________

Step-by-step explanation:

_______________________________

12 = (n/100) * 80 ;

12 = (80n) /100 ; Solve for "n:

Note: 80/100 = (80/10) / (100/10) = (8/10) = 0.8 ;

12 = (0.8)n ;

↔ (0.8n) = 12

Multiply each side of the equation by "10" ; to get rid of the "decimal" ;

10 * (0.8n) = 10 * 12 ;

to get:

_______________________________

8n = 120 ;

Divide each side of the equation by "8" ;

to isolate "n" on ONE SIDE of the equation; & to solve for "n" ;

8n/8 = 120/ 8 ;

_______________________________

to get:

_______________________________

n = 15 .

_______________________________

Answer: " 15 % " .

_______________________________

→ " 12 is  15%  of 80 " .

Hope this helps!

Best wishes!

A business sells kicking tees by mail for 3 each the shipping charge is 5 the function p=n+5 shows how the number of tees n rela

melamori03 [73]

Answer:

When you buy 2 , 3 and 4 tees , price you pay are 10.33 unit price , 13 unit price and 15.667 unit price respectively.

Solution:

Information provided in the question seems to be less . so assuming following two things.

1)Given function p = n + 5 do not include shipping cost as shipping cost is also dependent on number of tees.

2)If shipping charges for 3 tees is 5 , then shipping charges of 1 tee is $\frac{5}{3}$

When you buy 2 tees , n = 2

Price = p = n+5 = 2+5 = 7

Shipping charges =( $\frac{5}{3}$ ) x 2 = $\frac{10}{3}$

So total price you pay for two tees = 7 + ( $\frac{10}{3}$ ) = 7 + 3.3333 = 10.3333 unit price.

When you buy three tees , n = 3

Price = p = n+5 = 3+5 = 8

Shipping charges =( $\frac{5}{3}$ ) x 3 = 5

So total price you pay for two tees = 8 + 5 = 13 unit price.

When you buy four tees, n = 4

Price = p = n+5 = 4+5 = 9

Shipping charges =( $\frac{5}{3}$ ) x 4 = $\frac{20}{3}$

So total price you pay for two tees = 9 + ( $\frac{20}{3}$ ) = 47/3 = 15.667 unit price.

Hence when you buy 2 , 3 and 4 tees , price you pay are 10.33 unit price , 13 unit price and 15.667 unit price respectively.

Complete the square to transform the quadratic equation into the form (x – p)2 = q.

ryzh [129]

The transformed equation is:

$(x-3)^2 = 23$

Step-by-step explanation:

We have to convert the equation in the form

$(x-p)^2 = q$

Given equation is:

$x^2-6x-8 = 6$

Adding 8 on both sides

$x^2-6x-8+8 = 6+8\\x^2-6x = 14$

In the given equation

a = x

b= ?

So,

$2.x.b = 6x\\b =\frac{6x}{2x}\\b = 3\\$

So 3^2 will be added on both sides

$(x)^2-6x+ (3) = 14+ (3)^2\\(x-3)^2 = 14+9\\(x-3)^2 = 23$

Hence,

The transformed equation is:

$(x-3)^2 = 23$
