Answer:

The answer is c) 44 cm

Step-by-step explanation:

480= 20+b/2 x 15

480 x 2 = 20 + b x 15

960/15 = 20 + b

64 = 20+ b

64- 20 = b

44 = b

Hence the other parallel side is 44 cm

How many solution does -3 (4 - 3x) = 9x - 12

daser333 [38]

Answer: infinite solutions

Step-by-step explanation:

(−3) (4) + (−3) (−3x) = 9x + −12

−12 + 9x = 9x + −12

9x − 12 = 9x − 12

9x − 12 − 9x = 9x − 12 − 9x

−12 = −12

−12 + 12 = −12 + 12
