Answer:
6a³
Step-by-step explanation:
a⁴ + 9a³ - 10a² + 8a⁴ + X + a = 9a⁴ + 15a³ - 10a² = a
9a⁴ + 9a³ - 10a² + X + a = 9a⁴ + 15a³ - 10a² = a
9a³ + X + a = 15a³ = a
6a³ = X
checking: a⁴+ 8a⁴ + 6a³ = 15a³
9a⁴= 9a³
= a
P=10
Explanation
2p+p+90+100+140=360
3p+330=360
-330. -330
3p=30
P=10
First you add the numbers
6/2*3
Now you calculate the expression
6/2*3
The answer is 9, therefore 9 is your answer
