Answer:

Quadrilateral

Step-by-step explanation:

In the sandbox, opposite sides are equal.

However, using Pythagoras Theorem

14^2\neq 12^2+8^2\\196 \neq 208

Therefore, the sandbox cannot be a rectangle since if it were, each triangle must be a right triangle.

In the triangle

  • If c^2=a^2+b^2,  C is a right angle 
  • If c^2, C is an acute angle 
  • If c^2>a^2+b^2 , C is an obtuse angle 

Since 198, Angles C and X are acute angles.

Therefore, the sandbox does not satisfy the properties of any known quadrilateral. It is simply a quadrilateral-shaped sandbox.

If five times the successor of a number is added to an original number the sum is 83
Alexus [3.1K]

Answer:

Let the original number be x

Successor is defined as the number which comes immediately after a particular number.

also, the  successor of a whole number is the number obtained by adding 1 to that number.

Then, the successor of a number x is, x+1

As per the given condition :

we have;

5(x+1)+x =83

Using distributive property on LHS (i.e, a\cdot(b+c)=a\cdot b+a\cdot c )

Then, we have

5x+5+x=83

Combine like terms;

6x+5=83

Subtract 5 from both the sides we get;

6x+5-5=83-5

Simplify:

6x=78

Divide both side by 6,

\frac{6x}{6} =\frac{78}{6}

Simplify:

x =13

Therefore, the original number x is, 13
