Perfect square is
a²+2ab+b²
so just take the square root of the end ones and add then double to get middle term
A.
m+10=10m, doubled is 20m
nope
B.
m+5=5m, doubled is 10m, yep
C.
m+2√15=fancy thing that won't get to 36m
D.
m+12=12m, doubled is 24m, yep
B and D
Answer:
c+d
Step-by-step explanation:
c as the liters of water in the bucket, and d as the liters of water the jar more.
Together, you have to use addition to answer the question.

Volume of a cube is edge^3
Let the smaller cube = e^3 = 1e
Larger cube = 4e^3 = 64e
The ratio would be 64:1
Usually, we use the number line to solve inequalities with the symbols,
<
,
≤
,
>
, and
≥
.(the second and last one was rather hard to find on my keyboard) In order to solve an inequality using the number line, though, just turn
the inequality sign to an equal sign. Then, solve the equation. Next step,
graph the point on the number line (remember to graph as an open circle if the
original inequality was <, or >). The number line should now be
divided into 2 regions, one to the left of the graphed point, and one to the
right of said point.
After that, pick a point in both regions and "test" it, check to see if it satisfies
the inequality when plugged in for the variable. If it does, draw a darker line from the point into that region, with an
arrow at the end. That is the solution to the equation: if one
point in the region satisfies the inequality, the entire region will
satisfy the inequality.
I had to check back in an old textbook to remember all of that. Sorry about the earlier answer. That was rather foolish to do so without actually understanding the question.
Answer:
2/5 * pi radians = 72 degrees
Step-by-step explanation:
To convert radians to degrees, we multiply by 180/pi
2 * pi/5 * 180/pi =
The pi/pi cancels leaving
2/5 * 180
360/5
72
2/5 * pi radians = 72 degrees
