Answer:
Area of the figure = 109 cm. square
Step-by-step explanation:
The radius of the semi circle is 12 ÷ 2 = 6 cm.
Area of the semi circle = 
The radius of the quarter circle is 6 cm.
Area of the quarter circle = 
The area of the rectangle = 12 × 2 = 24
The area of the figure = 18π + 9π + 24 = 108.78 ≅ 109 cm. square
1.13 I hope I helped , enjoy it ‘!
24. 9×4=36 4×-3=12 so 36+(-12)=24
Answer: 44.064
Step-by-step explanation:
That's not an equation, and it doesn't ask any question. As it stands, there's nothing to "solve".
You may have been given an assignment to "simplify" it ... make it prettier and less complicated.
In order to do that, let's pretend for a moment that you're asked to add up a list that says:
4 chickens + 6 cows + 5 cows + 6 cows
I'm convinced that you would have no trouble at all adding up this list. You would
know right away that you can add up all the cows into one number, but you can't
add cows to chickens. You would simplify the list,and it would become <em>
4 chickens + 17 cows</em>.
And now that you understand that, you're all ready to simplify the expression
in your question. Just add up all the 'y's into a single number, but you can't
add 'y's to 'x's.
When you're done, you have 4x + 17y, and you're done. That's all you can do with it.
