Answer:

Heptagon, Irregular Polygon, and Concave

Step-by-step explanation:

From The figure shown in the picture we can see that it has the following characteristics. These characteristics are the following

  1. 7 straight sides
  2. 2- 90° angles
  3. 2 angles less than 90°
  4. 2 angles greater than 180°
  5. 1 angles greater than 90° but less than 180°

Based on these characteristics we can say that the figure meets all the requirements to be classified as Heptagon, Irregular Polygon, and Concave

<u>Heptagon:</u> are figures with 7 straight sides and 7 angles

<u>Irregular Polygons:</u> are polygons that can have sides of any length and each interior angle can be of different angles

<u>Concave:</u> are polygons that have one or more interior angles bigger than 180°

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Solve by factorising<br><br><img src="https://tex.z-dn.net/?f=x%5E%7B2%7D" id="TexFormula1" title="x^{2}" alt="x^{2}" align="abs
Paladinen [302]

Step-by-step explanation:

\underline{ \underline{ \text{Solving \: a \: quadratic \: equation \: by \: factorisation \: method}}} :

In this method , the second order of polynomial ax² + bx + c is factorised and expressed as the product of two linear factors. Then each linear factor is separately solved to get the required solutions of the equation by applying zero factor property. In zero factor property , if p•q = 0 , then either p = 0 or q = 0 . In other words , if the product of two numbers is 0 , then one or both of the numbers must be 0.

\underline{ \underline{ \text{Let's \: solve}}} :

\tt{ {x}^{2}  + 16x +  55 = 0}

Here , we have to find the two numbers that multiplies to 55 and adds to 16.

⤑ \tt{ {x}^{2}  + (11 + 5)x + 55 = 0}

⤑ \tt{ {x}^{2}  + 11x + 5x +  55 = 0}

⤑ \tt{x(x + 11) + 5(x + 11) = 0}

⤑ \tt{(x + 5)(x + 11) = 0}

Either :

\tt{x + 5 = 0 \: \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \: Or :  \:  \:  x + 11 = 0}

\sf{⟶ x  = 0 - 5} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \:⟶  x =  0 - 11

\tt{⟶x =  - 5 } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:     \:  \:⟶   x =  - 11

\red{ \boxed{ \boxed{ { \tt{Our \: final \: answer :  \boxed{ \underline{  \bold{ \tt{x  =  - 5 \: , - 11}}}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ

PLS HELP!
wolverine [178]

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

Diagonal=\sqrt{length^2+width^2}

Diagonal=\sqrt{(50)^2+(55)^2}

Diagonal=\sqrt{2500+3025}

Diagonal=\sqrt{5525&#10;}

On further simplification, we get

Diagonal=74.3303437

Diagonal\approx 74.3

Therefore, the length of the required fencing is 74.3 yards.

-3x+3y=12<br> Y=x+4<br> Whats the soultion
lisov135 [29]

The system of equations has infinitely many solutions

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

-3x + 3y = 12 ------- eqn 1

y = x + 4 --------- eqn 2

We have to find the solution to the system of equations

We can use substitution method

Substitute eqn 2 in eqn 1

-3x + 3(x + 4) = 12

-3x + 3x + 12 = 12

-3x + 12 = -3x + 12

If we have terms with same terms on both sides of equal sign, then we have infinitely many solutions

Thus the system of equations has infinitely many solutions

write and solve an equation to determine the length of a rectangular prism with a width of 4 feet ,a height of 6 feet ,and a vol
Tasya [4]

Answer:

3.5ft

Step-by-step explanation:

To calculate the volume of something, you need to know the formula. Length x width x height. You already know the width, and the height, so you need to find the length.

4ft x 6ft x 3.5ft = 84ft^3
