Please help me I will give you extra points and the brain thing
vovangra [49]

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

                                                       n² + n = 30

Subtract 30 from both sides:  n² + n - 30 = 0

Factorize:                               (n - 5)(n + 6) = 0

Therefore                                                 n = 5 or -6

As n > 2, then n = 5 only

Pre college need help number 3
lubasha [3.4K]

Answer:

B) No solution

Step-by-step explanation:

Adding two numbers together for a signle result cannot result in two different numbers. Example.

-2 + 3 = 1

-2 + 3 ≠ 4

You can also use math. Using substitution will result in simplyfying -y and y, creating 0 with no variable to solve for.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

The diagram shows 2 congruent regular polygons joined together. Work out the number of sides of each polygon. The exterior angle
Svetlanka [38]

Answer: There are five sides in a polygon.

Step-by-step explanation:

Since we have given that

Measure of exterior angles = 72°

We need to find the number of sides of  polygon.

As we know the formula for "Number of sides of polygon".

Number of sides is given by

\frac{360^\circ}{72^\circ}\\\\=5

Hence, there are five sides in a polygon.
