Answer:

114 ft

Step-by-step explanation:

We split the figure into two rectangles. The long triangles perimeter is equal to 30 + 30 + 9 + 9 = 78. Then, the top triangle is equal to 9 + 9 + 9 + 9, which is equal to 36. Then to find the perimeter of the entire figure, we add these two shapes together, 78 + 36, which gets us to our final answer, 114 ft.

Solve the equation, showing each step of the solution.<br> -3x + 25 = 40

grin007 [14]

Answer:

x= -5

Step-by-step explanation:

-3x + 25 = 40

you want to put x terms on one side, numbers on another side

subtract 25 on both sides

-3x = 15

divide both sides by -3

x= -5

If 32x+1 – 3x+5, what is the value of x?<br> N<br> w<br> оооо<br> o

PSYCHO15rus [73]

$\boxed{x=\frac{4}{35}}$

<h2>Explanation:</h2><h2 />

Here we have the following equation:

$32x + 1 = - 3x + 5$

So let's follows these steps:

Step 1: Add 3x to both sides:

$32x + 1 +3x= - 3x + 5+3x \\ \\$

Step 2. Combine like terms:

$32x + 3x + 1 = - 3x+3x + 5 \\ \\ 35x+1=5$

Step 3. Subtract -1 from both sides:

$35x+1-1=5-1 \\ \\ 35x=4$

Step 4. Divide both sides by 35:

$\frac{35}{35}x=\frac{4}{35} \\ \\ \\ \boxed{x=\frac{4}{35}}$

reflection symmetry is the quality a design has if it maintains all characteristics when it is rotated about an axis lying in it

OlgaM077 [116]

Answer:

True if reflection over a line.

Step-by-step explanation:

Given that there is a reflection symmetry. We have to discuss about the quality of the design.

By reflection , we mean it can be either on a line or on a point.

If symmetry is on a line, then we get a mirror image of the original one keeping the line of symmetry as mirror. Hence in this case when rotated about axis of symmetry lying it its plane the original design would be maintained.

Examples are : Circles, ellipses, hyperbolas, etc.

Reflection about a point is obtained by keeping equal distance form the point.

For example, reflection of (1,1) over origin would be (-1,-1)

Here the rotation quality may not apply

Explain why y +1 = 1.2(x+2) and y-5= 1.2(x – 3) represent the same line, despite having

andrew11 [14]

Answer:

You can manipulate both equations into y = mx + b format and end up with the same result of y = 1.2x + 1.4

Step-by-step explanation:

y + 1 = 1.2(x + 2)

y = 1.2x + 2.4 - 1

y = 1.2x + 1.4

y - 5 = 1.2(x - 3)

y = 1.2x - 3.6 + 5

y = 1.2x + 1.4

So essentially, they're the same equation but in different forms.
