Answer:

56.25

Step-by-step explanation:

6*9=54+2.25= 56.25

Answer:

$56.25

Step-by-step explanation:

So first off we have 6 1/4 hours being worked at the rate of 9 dollars and hour. 6 hours multiplied by 9 dollars will give you 54 dollars. After that all we need to do is get a quarter of 9 dollars, which is $2.25 adding this to our original number of 54, we have $56.25. Hope this helps!

Answer:

−x^2 − 8x

Step-by-step explanation:

Lets say y is the missing value

Add -x^2 to both sides.

x^2+8x+y+−x^2=0+−x^2

8x+y=−x^2

Add -8x to both sides.

8x + y + −8x = −x^2 + −8x

y = −x^2 − 8x

So the whole equation would be

x^2 + 8x + −x^2 − 8x = 0

Answer:

The area  of square in terms of x = 16x² -24x + 9

Step-by-step explanation:

It is stated in the question that the length of a square = 4x - 3

Formula to find the area of the square is

Area = length²

Area = ( 4x - 3 )²

by using ( a - b )² = a² + b² - 2ab

here a = 4x and b = -3

So,

(4x)² + (-3)² - 2(4x)(3)

16x² + 9 - 2(12x)

16x² + 9 - 24x

16x² -24x + 9

The area  of square in terms of x = 16x² -24x + 9

Answer:

The area  of square in terms of x = 16x² -24x + 9  

Step-by-step explanation:  

It is stated in the question that the length of a square = 4x - 3  

Formula to find the area of the square is  

Area = length²

Area = ( 4x - 3 )²  

by using ( a - b )² = a² + b² - 2ab  

here a = 4x and b = -3  

So,  

(4x)² + (-3)² - 2(4x)(3)  

16x² + 9 - 2(12x)  

16x² + 9 - 24x  

16x² -24x + 9

The area  of square in terms of x = 16x² -24x + 9

Answer:(2x+1)x=45

x=4.5

4.5*2+1=10

Step-by-step explanation:

Answer: Bertha nació el 18 de septiembre de 1990.

Step-by-step explanation:

Gonzalo nació el 18 de septiembre de 1945.

Bertha nació cuatro décadas y un lustro después.

Una década son 10 años

Un lustro son 5 años

Entonces 4 décadas y un lustro son:

4*10 años + 5 años = 45 años

Esto significa que Bertha nació 45 años después que Gonzalo.

Entonces si Gonzalo nació en 1945, Bertha nació en el año:

1945 + 45 = 1990

Bertha nació el 18 de septiembre de 1990.

La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.

A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.

For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945

Bertha born after 4 decades and 5 years of Gonzelo's birth.

4 decades = 4 times 10 = 40 years

Thus, 4 decades + 5 years = 40 + 5 = 45 years.

45 years after 1945 uis 1945 + 45 = 1990

Thus, date of birth of Bertha is 18th Sept. 1990

Answer: x+3+ 18/x-3

Step-by-step explanation:

The complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)

In mathematics, divides left-hand operands into right-hand operands in the division operation.

To divide using synthetic division, we follow these steps:

Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.

Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.

Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.

Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.

Repeat this process until you have found the coefficients of all the terms in the quotient.

Using this process, we can divide (x² +9) by (x-3) as follows:

The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:

(x² + 9) / (x-3) = x + 3 + 18/(x-3)
