Hello!

Answer: </h2>
<h2>
Explanation:</h2>
3(x + 3) = 18
<em>⇒ Step 1 - </em><em>Multiply everything in the brackets by 3:</em>
3x + 9 = 18
⇒ <em>Step 2 - </em><em>Subtract 9 from both sides of the equation:</em>
3x + 9 = 18
- 9 - 9
3x = 18
⇒ <em>Step 3 - </em><em>Divide both sides of the equation by 3. </em>

x = 6
2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.
Answer:
Option A, m = 10
Step-by-step explanation:
<u>Step 1: Divide both sides by 6</u>
6m / 6 = 60 / 6
m = 10
Answer: Option A, m = 10
X = +- sqrt 5 or 2.2361. no problem
