Please answer this question, i need it to be explained also. please

2.64

Step-by-step explanation:

54.2 - 47.6 = 6.6

Selena's tree is 6.6 CMS taller.

We need to convert that into inches, I believe.

1 cm = 0.4 inches

6.6 cms into inches = 2.5984252, est. 2.6

Not an answer choice, another way to find this is

6.6 x 0.4 = 2.64

Which is an answer choice, so your answer should be the last one, 2.64.

step-by-step explanation:

d

let m = monomial

let t = trinomial

monomial times a trinomial = another trinomial.
