Part 1:

6(x-5) = 5(x+5) (x = 55)

4y + 2 (-3 + 2y) = 1-y (x = 7/9)

Part 2:

4(a-6) = 8a - (4a-24) (No Solution)

4(2x-8) = 8(x-8) (No Solution)

2(3x-3) = -6x-6 (Identity (x = 0))

Scrat [10]

Combined area is 5.454 × 10^7 km²

Step-by-step explanation:

Step 1: Find the combined area of Asia and Europe.

Area of Asia = 44,600,000 km²

Area of Europe = 9,943,106 km²

⇒ Combined Area = 44,600,000 + 9,943,106

= 54,543,106 km²

Step 2: Convert to one significant figure.

54,543,106 = 5.454 × 10^7 km² (Dividing and multiplying by 10^7)

So firstly, reverse the signs in (6x^2 + 8x - 1) and change the minus sign to a plus sign:

$\begin{alignedat}{2} 4x^2-9x+7\\ +(-6x^2)-8x+1\end{alignedat}$

Next, combine like terms:

$\begin{alignedat}{3} 4x^2-9x+7\\ +(-6x^2)-8x+1\\-2x^2-17x+8\end{alignedat}$

<u>The difference is -2x^2 - 17x + 8</u>
