Answer:
The simplified expression for the area of the stated square is A (x) = (2x² - 4)²
Step-by-step explanation:
To solve this problem first you need to think about the realationtship beetwen Area and side of a square. Then Area = (side)².
Here we have that side is equal to 2x² - 4. Then A(x) = (2x² - 4)² which is the expression of a square of a binomial. Then A(x) = 4x^4 - 16x² + 16. If you look at this two expressions, the first one is the simplified one. So,
A(x) = (2x² - 4)²
Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.
Answer:
12. 56
Step-by-step explanation:
The area of a circle is given by pi×r^2
where r is the radius. The question states That we should use 3. 14 in place of pi.
Area=3. 14×r^2
=3. 14×2^2
=3. 13×4
=12. 56
