Hello!

❖ Mean = 4.8 Median = 4.5
The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.8
To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:
4 + 5 = 9
9 ÷ 2 = 4.5
Step-by-step explanation:
I think what you have to do is group the numbers such as x^2 and -3x^2 and let’s just say since you have 5x^2y thrown in there it wouldn’t be a like term with x^2 and -3x^2 I’m sorry if this didn’t make sense I tried
Answer:
Step-by-step explanation:
PQ=24
PS=19
PR=42
TQ=10
QR=19
SR=24
PT=21
SQ=20
m∠QRS=180-m∠PQR=180-106=74°
m∠PQS=m∠QSR=49°
m∠RPS=m∠PRQ=m∠QRS-m∠PRS=74-35=39°
m∠PSQ=m∠RQS=m∠PQR-m∠PQS=106-49=57°
m∠PQR=106°
m∠ QSR=49°
M∠PRS=35°
That in algebraic form would be
Subtract 15 to both sids and you get
Multiply 2 on both sides and you get
n = -12
14.5 x 22.75 = 329.88
4 x 9.66 = 38.64
TOTAL = 368.52 square feet
