4,000,000 and 20,000,000 miles²
let x be the area of one desert then 5x is the area of the other
sum = x + 5x = 24,000,000
6x = 24,000,000
divide both sides by 6
x = 4,000,000
one desert is 4,000,000 miles²
and the other is (5 × 4,000,000)= 20,000,000 miles²
Decimals from 7.0 to 8.4 with an interval of 0.2 between each pair of decimals
We start with 7.0 and keep adding 0.2 till we get 8.4
7.0 + 0.2 = 7.2
7.2 + 0.2 = 7.4
7.4 + 0.2 = 7.6
7.6 + 0.2 = 7.8
7.8 + 0.2 = 8.0
8.0 + 0.2 = 8.2
8.2 + 0.2 = 8.4
So, the decimals from 7.0 to 8.4 with an interval of 0.2 are
7.2, 7.4, 7.6, 7.8, 8.0, 8.2
Answer:
6. Find the product for both sets of polynomials below by multiplying vertically. (4 points: 2 points for each product)
A)
4x^4 - 4x^3 - 16x^2 + 16x
B)
4x^4 - 4x^3 - 16x^2 + 16x
7. Are the two products the same when you multiply them vertically? (1 point)
Yes, the two products are the same when you multiply them.
Making a Decision:
8. Who was right, Emily or Zach? Are the products the same with the three different methods of multiplication? (1 point)
Emily was right, the products are the same with all three different methods of multiplication.
9. Which of these three methods is your preferred method for multiplying polynomials? Why? (1 point)
I prefer the table method because it is easier to understand what is going on, know where and what to do, and it is nicely and neatly laid out in front of me.
