Since you cannot add numbers which have x to the power of something and normal x, A and B are incorrect. C is also incorrect because I don't even know how you could get that number.
D is correct.
(14x2 + 7x) + 9x2 - you don't even need the brackets, so
14x2 + 7x + 9x2
(14x2 + 9x2) + 7x
23x2 + 7x

Answer: option D

Step-by-step explanation:

X+8=-2

x= -2-8 (you should make x the subject so you switch the +8 to the other

x= -10 side which becomes -8)

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D

<h2>Explanation:</h2><h2 />

The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:

$A=b\times h \\ \\ A:Area \\ \\ b:Base \\ \\ h:Height \\ \\ \\ CB=b \\ \\ AB=h$
