-3a(a^2-10a+25)= expand it and it has to be in polynomial form

Step-by-step explanation:

Multiply each term in the parentheses by -3a

Calculate the product

Multiplying two negatives equals a positive

Calculate the product

Hope this helps...

Best regards!!

(1,4) is on graph of f(x)

f(1) = 4

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

it would take 7/10 of an hour too fill the pool.
