The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,

an = a1 + (n - 1) d

Solving for the 23rd term,

an = 4 + (22) 5 = 114 seats

Therefore, the answer is there are 114 seats on the 23rd row.

Given the triangle that has a base of five less than triple the height. The height is 2x+6.

Deffense [45]

Answer:

Step-by-step explanation:

H = 2x+6 - the hight

3H = 3(2x+6) - triple the hight

3H-5 = 3(2x+6) - 5 - five less than triple the height

Area of triangle: A = 0.5BH

B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13

H = 2x+6

So:

A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78

A = 6x² + 49x + 78
