Answer: Hence, Option (6) and (8) are correct as their value is also "-8".
Step-by-step explanation:
Since we have given that
First we need to solve to get the value of 'x' :
Therefore, x=-8
Now, we will check all the options :
1) 4x+8=24
2) 9x+18=-24
3) 4x+12=-24
4) 18x+36/2=-24
5) 4x=-36
6) 4x=-32
7) x=-9
8) x=-8
Hence, Option (6) and (8) are correct as their value is also "-8".
Answer:
16c² + 32cd + 16d²
Step-by-step explanation:
A polynomial is an expression consisting of variables and coefficients. For example, is an example of a cubic polynomial.
Area of a square = side length x side length
Therefore, given the side length of this square is 4c + 4d, then the area can be expressed as:
area = (4c + 4d) x (4c x 4d) = (4c + 4d)²
If we expand the brackets we get:
area = 16c² + 32cd + 16d²
