There are 19 blue balls in a box. there are 5 less than twice as many red balls. how many balls are in the box? ​

9

step-by-step explanation:

5 less than twice red balls

5×2=10

19-10=9

a = l x w

a / l = (l x w) / l

a / l = w

w = a / l = 108 / 12

w = 9 inches

next , the one inch border reduces the length and the width each by 2 inches, so l and w now equal 10 and 7

a = l x w = 10 x 7 = 70 sq inches left for painting
