Answer:

147+25=172

Step-by-step explanation:

Have a nice day!

Brainliest me pls

Answer:

A = 147

Step-by-step explanation:

A + 25 = 172

subtract 25 from both sides

A + 25 - 25 = 172 - 25

A = 147

A’B’C’D' will be a reflection of figure ABCD about line f

A reflection over a line l(notation l) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line.

reflection of point D will be D' if the distance between point D and line f is the same as the distance between point D' and line f

let us consider point (10,0) on line f for our convenience. we will calculate each distance from this point (10,0)

distance is 2 units from both the points D and D'

reflection of point C will be C' if the distance between point C and line f is the same as the distance between point C' and line f

distance of point C from line f= distance of point C' from line f

[tex]\sqrt{(14-10)^2 + (-2-0)^2} = \sqrt{(10-8)^2+ (4-0)^2} =\sqrt{20}[/tex]

similarly, point A and B will also be equidistant from line f

therefore,  A’B’C’D' will be a reflection of figure ABCD about line f.

It will take them 2 hours and 22 minutes to working together.

Here,

Joan paint the porch in 5 hours.

Jan can take 4 hours to paint the porch.

We have to find the time to take them working together.

What is Fraction?

A fraction simply tells us how many parts of a whole we have.

Now,

Let x is number of hours to take them working together.

Then, 1/x is how much of the porch they can paint together in 1 hour.

Joan paint the porch in 5 hours.

Then, Joan can take 1 hour to paint the 1/5 part of porch.

Jan can take 4 hours to paint the porch.

Then, Jan can take 1 hour to paint the 1/4 part of porch.

To find how much of the porch they can paint together in 1 hour, we can add together;

[tex]\frac{1}{5}+ \frac{1}{4} = \frac{1}{x} \\\\\frac{4+5}{20} = \frac{1}{x} \\\\\frac{9}{20} = \frac{1}{x}\\\\x = 20.22[/tex]

Hence, It will take them 2 hours and 22 minutes to working together.

The value of AG is 37cm

From the diagram shown, we have that;

But;

AG + GB = AB

Let's substitute the values

3x + 3 + 11x + 6 = 166

collect like terms

3x + 11x + 9 = 166

14x = 166 - 9

14x = 157

Make 'x' the subject

x = 157/ 14

x = 11. 2cm

But line AG = 3x + 3 = 3 ( 11. 2) + 3 = 33. 6 + 3 = 37cm

The dimensions of the cropped photo will be 9 inches by 9 inches

Step-by-step explanation:

From the formula of area of square

Length x width = area

[tex]x^{2}[/tex] = area

But we are given the equation as

[tex](x+2)^{2}[/tex] = 121

The equation gives the measures of the cropped dimension as "x". This means we need to solve the equation

[tex](x+2)^{2}[/tex] = 121

[tex]x^{2}[/tex] + [tex]2^{2}[/tex] + 2(x) (2) = 121

[tex]x^{2}[/tex] + 4 + 4x = 121

[tex]x^{2}[/tex]  + 4x -117 = 0

[tex]x^{2}[/tex]  + 13x - 9x -171 = 0

x( x+13) -9 (x+13) = 0

(x+13)(x-19) =0

This means

x = 9, -13

Since, dimension can't be negative. So, the measure of dimension would be 9 inches by 9 inches

Answer:

(3.2 × 10²) times as large

Step-by-step explanation:

First, set up an equation:

(8 × 10³) ÷ (4 × 10²)

Using the laws of exponents, we know that when two exponents with the same base are being divided by each other, the exponents subtract from each other:

(8 × 4) × (10³⁻²) = (32 × 10¹)

Move the decimal one space to the left, which increases the exponent by 1:

(3.2 × 10²)

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

(8)

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (8, 2)

m = [tex]\frac{2-2}{8+3}[/tex] = [tex]\frac{0}{11}[/tex] = 0

A slope of zero indicates the line is horizontal and parallel to the x- axis with equation

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (- 3, 2) and (8, 2) with y- coordinates 2, thus

y = 2 ← equation of line

(9)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 3, 2)

m = [tex]\frac{2-1}{-3+6}[/tex] = [tex]\frac{1}{3}[/tex] , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 2) , then

2 = - 1 + c ⇒ c = 2 + 1 = 3

y = [tex]\frac{1}{3}[/tex] x + 3 ← equation of line
