Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)
= 12 x 57.6 grams
= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams

Step-by-step explanation:
Adjust based on LCM (15):
Answer:
a) 8x^2 + 4x + 9
Step-by-step explanation:
To find the total number of red and pink geranium pots, we need to add the two expressions given for the number of pots for red and pink respectively.
x (7x - 2) + (x + 3)^2
Expanding x (7x - 2) gives (7x^2 - 2x)
Expanding (x + 3)^2 gives (x^2 + 6x + 9)
Adding the like terms in these two expanded expressions:
(7x^2 - 2x) + (x^2 + 6x + 9)
= 7x^2 + x^2 + 6x - 2x +9
8x^2 + 4x + 9
3.5 is the answer to your problem
