Melissa and her mom go on a road trip. they drive 87 kilometers before lunch. they drive 59 kilometers after lunch. estamate how many more kilometers they drive before lunch than after lunch by rounding to the nearest 10 kilometers.

Melissa and her mom drive 30km more before lunch

Step-by-step explanation:

We know that before lunch they drive 87km and 59km after lunch.

To know how many more kilometers drive before lunch we subtract the kilometers driven before lunch with the amount of kilometers driven after lunch

As we have to round it to the nearest 10 we round it to 30

Melissa and her mom drive 30km more before lunch

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
