we know that
distributive property of multiplication over addition:

now, we will verify each options
option-A:
3 × (4 + 5) = (3 × 4) + (3 × 5)
We can see that both sides match with property
so, this is TRUE
option-B:
3 × (4 + 5) = (3 + 4) × (3 + 5)
We can see that right side does not match with property
so, this is FALSE
option-C:
3 × (4 + 5) = (3 × 4) + 5
We can see that right side does not match with property
so, this is FALSE
Answer:
7 x 6 x 5 = 210
Step-by-step explanation:
its a combination's problem.
7 horses are eligible for first place.
6 of those are eligible for 2nd given that one of the 7 finished first.
similarly 5 of the remaining are eligible for 3rd place given 2 horses have taken the first 2 spots.
therefore 7 x 6 x 5 possible combinations = 210 combinations.
