Nora created a tiled mosaic for display in her local art museum. The number of tiles in the first 18 rows of the mosaic form an arithmetic sequence. The first row of the mosaic has 5 tiles and the second row had 8 tiles. A. Write a explicit formula representing this sequence

B. Determine the number of the tiles in the 14th row

ANSWERS:

A. an=5+3(n-1);44 tiles

B. an=3+5(n-1); 48 tiles

C. an=3+5(n-1);44 tiles

D. an=5+3(n-1);48 tiles

Show your work please!!! Thanks

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

step-by-step explanation:

i got the answer right on edg.

congruent: (geometry) (of figures) identical in form; coinciding exactly when superimposed.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
