Answer:
h<-8/3
Step-by-step explanation:
collect like terms
-10h+7h>9-1
3h>8
divide both sides of the inequality by -3 and flip the inequality sign
h<-8/3
Answer:
x = 12
Step-by-step explanation:
42 + 4x = 90 ( as it is right angle)
transpose to find x
4x = 90 - 42
4x = 48
x = 48/4
x = 12
Translating into a mathematical equation:
n + n^2 = 72
Rewriting, n^2 + n - 72 = 0
Factoring, (n+9)(n-8) = 0
Solving for n: n = -9 or n = 8
You must check both answers before accepting one, the other or both.
Example: suppose we check out n = 8. Then 8 + 8^2 = 72 is true, and n = 8 is a solution. Is n = -9 a solution? Try it.
