What is a good estimate and the actual measurement for this angle measurement? A. 110 and 109 B. 95 and 96 C. 90 and 91 D. 70 and 71

Answers

The good estimate, as well as the actual measurement for the given angle, is 110° and 109°.

What is a good estimate?

In construction, a good estimate is an approximate value of a number that makes it faster to make cognitive deductions.

On the other hand, the actual measurement is the exact measurement of an angle or shape when the appropriate measuring tools are being used.

From the diagram, the angle is an obtuse angle because it is more than 90° since it extends more than its perpendicular axis(90°), but it is less than 180°.


Therefore, we can conclude that the good estimate, as well as the actual measurement for the given angle, is 110° and 109°.

Solve 12x^2+5x-4=12^2x+6

Answers

Answer:

okay so we need to solve for x.

--

FIRST STEP:  12x^2+5x-4=12^2x+6 would turn into x2 + 5x - 4 = 2x + 6 so it'd have equal bases.

SECOND STEP: move any number with "x" in it to the left side. it ends up as  x2 + 3x - 4 = 6

THEN, we use the AC method to eliminate any unnecessary numbers.

you should end up with ( x - 2) (x + 5) = 0

SO, the answer is your third option. ( x = 2, x = -5)

Step-by-step explanation:

Answer:

x = 2, x = -5

Step-by-step explanation:

since 16 is five less that means whatever the equation equals it will be 16 which is why 16 is in the first part

Simplify the polynomial by writing each of its term in standard form. 1.5xy^2 *(-4)xyz-4mnk*5m^2 n^3 k

Answers

The simplified polynomial by writing each of its term in standard form is:

[tex]-20m^{3}[/tex] [tex]n^{4}[/tex][tex]k^{2}[/tex] - [tex]6xy^{3z}[/tex]

What is polynomial?

A polynomial is a mathematical expression that consists of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, multiplication, and non-negative integer exponents.

To simplify the given polynomial by writing each of its term in standard form, we need to expand the products and arrange the terms in decreasing order of their degree.

First, let's expand the product [tex]1.5xy^{2}[/tex] *(-4)xyz:

[tex]1.5xy^{2}[/tex] *(-4)xyz = ([tex]-6xy^{3z}[/tex])

Next, let's expand the product -4mnk*[tex]5m^{2}[/tex] [tex]n^{3}[/tex] k:

-4mnk*[tex]5m^{2}[/tex] [tex]n^{3}[/tex]k = ([tex]-20m^{3}[/tex] [tex]n^{4}[/tex] [tex]k^{2}[/tex])

Now, we can write the simplified polynomial by adding the two terms we obtained and arranging them in decreasing order of their degree:

[tex]-20m^{3}[/tex] [tex]n^{4}[/tex] [tex]k^{2}[/tex] - 6xy^3z[tex]6xy^{3z}[/tex]

Therefore, the simplified polynomial by writing each of its term in standard form is:

[tex]-20m^{3}[/tex][tex]n^{4}[/tex] [tex]k^{2}[/tex] - [tex]6xy^{3z}[/tex]

Answers

Answer:

Step-by-step explanation:

12/20 = 3/x

solve for x

x=5

Answer: x is 5

Step-by-step explanation: These two triangles are similar (meaning same shape but different size.) To find x, we must first decrease the scaling. The original triangle is 3 and x sides. Being scaled, it is now 12 and 20. 12 divided by 4 is 3, so that's the first side, and being equivalent, 20 divided by 4 is 5, so therefore the triangle has been scaled by 4 units. Therefore x side is 5.

A photograph has a length that is 2 inches longer than its width. There is a 1-inch frame surrounding the photograph. Which expression represents the area of the entire photograph and frame combined?

Answers

The expression representing the area of the entire photograph and frame combined is A = x²+4x+3.

What is Area?

Area is the amount of space taken up by a plane shape.

To find an expression for the area of the entire photograph and the frame combined, we use the formula below.

Formula:

A = L×W............. Equation 1

Where:

A = Area of the photograph and the frameL = Length of the photograph and the frameW = Width of the photograph and the frame

From the question,

Let the width of the photograph be x, The length of the photograph = (x+2) inchesL = (x+2)+1 = (x+3) inchesW = (x+1) inches

Substitute these values into equation 1

A = (x+3)(x+1)A = x²+x+3x+3A = x²+4x+3

Hence, The expression representing the area of the entire photograph and frame combined is A = x²+4x+3.
