Answer:
if we are simplifying, the answer is 6x⁴y²
Answer:
2.61
Step-by-step explanation:
Given:
The figure of two quadrilaterals.
In
In
To find:
Whether the figures are congruent, similar or neither.
Solution:
Ratio of corresponding sides are:
Similarly,
And,
Clearly, .
All corresponding sides are not proportional.
Therefore, the figures are neither similar nor congruent. Hence, third option is correct.
The result is
9

2
−
16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−
b
)
=

.
By applying this to our question, we obtain that:
(

⋅
(
