Answer:
42
Step-by-step explanation:
to find the perimiter youre gonna want to add up all the sides you already have,
so we have 4, 4, 11, and 6.
the reason we dont count the other 4 inside of the figure is because that is inside of it, so we would consider that perimiter
as we see there are other sides not labeled. we have to use that area four to help us.
for the top left side, we do 6 - 4 = 2
for the bottom right side, we do 11 - 4 = 7
then, as we see at the top right we have a four labeled, these look the same width so add a four.
and at the top left, we see another four so add that.
then, add up everything giving you 42.
i hope this helped! <3
Answer:
A
Step-by-step explanation:
2.14x - 12.18 = -5.76
Since the inverse operation of subtraction is addition, add 12.18 to both sides.
2.14x=6.42
Now, since the inverse operation of multiplication is division, divide both sides by 2.14
x=3
Answer:
4, 49
Step-by-step explanation:
If you find the square root of 4 it is 2, making it a perfect square.
if you find the square root of 49, it is 7.
finding a perfect square is easy, simply multiply a smaller number by itself, (7x7) or (2x2) and you will find that is the square root, usually, however there are always some exceptions. A number can always have a smaller square root like √10 is 3.16227766
