No thats only if your multiplying it gets confusing like that

The diagram for this problem is shown below. Point E is the intersection of the two diagonals and we know that:

Every internal angle of any rectangle measures 90 degrees, so:

So:

So the measure of angle BEC can be found as follows:
We know that triangle ΔCEB is an isosceles triangle because the diagonals of any rectangle measure the same. So

The sum of internal angles of any triangle add up to 180 degrees, so:

Answer:
1,4,9,16...
Step-by-step explanation:
It does not have a common difference between each consecutive term, therefore it is not an arithmetic sequence.
Answer:
p = 1.5 and q = 9
Step-by-step explanation:
Expand the right side then compare the coefficients of like terms on both sides, that is
4(x + p)² - q ← expand (x + p)² using FOIL
= 4(x² + 2px + p²) - q ← distribute parenthesis
= 4x² + 8px + 4p² - q
Comparing coefficients of like terms on both sides
8p = 12 ( coefficients of x- terms ) ← divide both sides by 8
p = 1.5
4p² - q = 0 ( constant terms ), that is
4(1.5)² - q = 0
9 - q = 0 ( subtract 9 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
The answer is D I’m pretty sure!? Hopefully you got it right!!!!!!!
