Answer:


(c) 4 small squares
Step-by-step explanation:
Given
<u>Small Square:</u>

<u>Large Square:</u>
i.e. twice as long as the small square
Solving (a): The area of the small square.
This is calculated as

So, we have:

Solving (b): The area of the large square.
This is calculated as

So, we have:


Solving (c): Number of small square to cover the large square
To do this, we simply divide their areas.
Let n represents the required number; n is calculated as:



<em>Hence, 4 small squares is required to cover the large square</em>
6x^2 should be one of them if i am not mistaken!
Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
(-6,0) is a point of an x- intercept in this function
