Answer:

Step-by-step explanation:

The exact value for the expression √52 – √13 + √117 given in the question above is 4√13

a√b + c√b = (a + c)√b

With the above information in mind, we can simplify the express given in the question above.

√52 – √13 + √117

Recall

√52 = √(4 × 13) = 2√13

√117 = √(9 × 13) = 3√13

Thus

√52 – √13 + √117 = 2√13 – √13 + 3√13

√52 – √13 + √117 = (2 – 1 + 3)√13

√52 – √13 + √117 = 4√13

Answer:

slope: 2 as we see, with every increase in x, y increase twice the more.

Step-by-step explanation:

The slope of the linear graph in the question obtained using the ratio of the rise and run of the line is 2.

Recall :

Slope = Rise / Run

From the graph :

Rise = y2 - y1 = 5 - (-1) = 5 + 1 = 6

Run = x2 - x1 = 2 - (-1) = 2 + 1 = 3

The slope of the graph can be expressed thus :

Slope = Rise / Run = 6 /3 = 2

Therefore, the slope of the line in the graph attached is 2

The equation which shows the true solution to the given logarithmic equation is,

[tex]x=1[/tex]

The power of the log rule says that the number written in the front of the logarithmic function can be raised to the power of the logarithmic function.

For example,

[tex]n\log_b(M)=\log_b(M)^n[/tex]

Given information-

The logarithmic equation given in the problem is,

[tex]3\log_2(2x)=3[/tex]

Using the power rule of the logarithmic function,

[tex]\log_2(2x)^3=3[/tex]

Using the exponent rule of the logarithmic function the above equation can be written as,

[tex](2x)^3=3[/tex]

Solve it further,

Answer:

y = 55°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

100° is an exterior angle of the triangle , then

y + 45° = 100° ( subtract 45° from both sides )

y = 55°

Rhombus has all sides equal. The total amount of paper that will be needed to cover the wall is 396 in².

Given to us

Each rhombus will be 6 inches tall and 4 inches wide.

A.)

The area of each rhombus can be found using the formula,

[tex]Area = \dfrac{1}{2} \times d_1 \times d_2[/tex]

We know that diagonals of the rhombus are of length 6 in and 4 in. therefore,

[tex]Area = \dfrac{1}{2} \times 6 \times 4\\\\Area = 12\ in^2[/tex]

Hence, the area of the single rhombus is 12 in².

We know that the wall is 11 feet long, also, 1 foot = 12 inches, therefore,

11 feet = 132 in.

Now, since the wall is 132 in long and the width of the rhombus is 4 in, therefore, the number of rhombi that will be needed,

[tex]\dfrac{132}{4} =33[/tex]

Hence, the number of rhombi that will be needed is 33.

We know the area of each paper rhombus, also, we know the number of rhombi that will be needed. Therefore,

[tex]33 \times 12 = 396\ in^2[/tex]

Hence, the total amount of paper that will be needed to cover the wall is 396 in².

Answer:it’s 10x + 12

Step-by-step explanation:

your welcome

The sum of ten times a number and 12 can be written as 10x + 12.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expression "ten times a number" can be represented as 10x, where x is the number.

So, "the sum of ten times a number and 12" can be written as:

10x + 12

This expression represents a mathematical operation where 10 times the number is added to 12.

Thus,

The sum of ten times a number and 12 can be written as 10x + 12.

Answer:

[tex]4x^2y-7xy+10xy^2[/tex]

Step-by-step explanation:

We have [tex]\left(6x^2y-8xy+7xy^2\right)+\left(3xy^2-2x^2y+xy\right)[/tex] and need to add them together.

Though complicated at first, we can simplify by taking out the parenthesis and making this whole question into one equation.

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

Now combine like terms, meaning you can only add the terms that have the same ending, in math, you cannot add numbers that have different exponents or variables.

Therefore:

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

[tex]6x^2y-2x^2y-8xy+xy+7xy^2+3xy^2[/tex]
