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
It has multiple functions but it should be close to the middle
Answer:
28
Step-by-step explanation:
4+6=10,10+6=16,16+6=22,22+6=28
Answer:
Step-by-step explanation:
A pentagon's angle all add up to 540
2j+6a = 24
5j+3a =21
multiply the 2nd equation by -2
-10j -6a = -42
add the 1st and the modified 2nd together
2j+6a = 24
-10j -6a = -42
---------------------
-8j = -18
divide by -8
j = 2.25
substitute into
2j+6a = 24
2(2.25) +6a =24
4.50 +6a =24
subtract 4.5 from each side
6a = 19.50
divide by 6
a = 3.25
