The IQR is the upper quartile-lower quartile. The way to determine this is finding the median of your numbers which is 53. Then you take the numbers higher than 53 and find the median of those which is 63.5. 63.5 is the upper quartile. Then you take the bottom half under 53 and find the median of those. The median of this is 53.5 53.5 is the lower quartile. Then just subtract 63.5-53.5 and you will get 10 as the IQR.

(a+2b)² ?????????????????????

lbvjy [14]

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

If m FDG = 50°, what is m FEG? 75° 50° 100° 25° Thank you!

The measure of the angle FEG is probably the same as the measure of the angle FDG. There is nothing saying that EF is parallel to DG, but if so, the measure of the angle FEG is also 50º.
When the diagonals of a trapezium with two parallel bases inside of a circle are drawn, they make the same angle measure with those bases.
