Answer:

r³ + 15r² - 10r - 4

Step-by-step explanation:

First, note you can remove the brackets, in this case they contribute nothing at all.

Then, group the like terms and add them, e.g., we have 3r³ and -2r², they add up to r³.

Finally, order them from greatest power of r to smallest power of r.

That's all!

11) Which is an example of Associative Property of Addition ?

vlabodo [156]

Answer:

D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.

Step-by-step explanation:

Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.

or, for any numbers A, B and C

A + ( B +C) = (A +B) + C

Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.

Given the graph, find the distance of GH. Round to the nearest tenth.

lord [1]

Answer:

GH = 6.3 units

Step-by-step explanation:

Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).

Distance between G and H = $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$G(-2, -3) = (x_1, y_1)$

$H(0, 3) = (x_2, y_2)$

$GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2}$

$GH = \sqrt{(2)^2 + (6)^2}$

$GH = \sqrt{4 + 36} = \sqrt{40}$

$GH = 6.3 units$ (nearest tenth)
