Fiona wrote out the description of each step for her multiplication of the binomial and trinomial (2x – 3)(5x2 – 2x + 7)

See below:

Step-by-step explanation:

2x times 5x^2 = 10x^3

2x times -2x = -4x^2

2x times 7 = 14x

-3 times 5x^2 = -15x^2

-3 times -2x = 6x

-3 times 7 = -21

answer: a.   one is a factor of every whole number since every number is divisible by itself.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
