Help please. I’m confused. I’ll thank u

 See Below

Step-by-step explanation:

(b) Make a table of white ovals and black ovals.  You will notice that

white starts with 3 and adds 3 to each design → 3 + 3(d - 1) = 3d

black starts with 4 and adds 4 to each design → 4 + 4(d - 1) = 4d

white ovals when design = 30   --->    3d = 3(30) = 90

black ovals when design = 100   --->   4d = 4(100) = 400

white ovals when design = 50   --->   3d = 3(50) = 150

black ovals when design = 50   --->   4d = 4(50) = 200

                                                                  TOTAL = 350

(c) Make a table of rods and squares.  You will notice that

rods start with 19 and add 12 to each design → 19 + 12(d - 1) = 12d - 7

squares start with 6 and add 4 to each design → 6 + 4(d - 1) = 4d + 2

rods when design = 15   --->    12d - 7 = 12(15) - 7 = 173

squares when design = 15   --->   4d + 2 = 4(15) + 2 = 62

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
