Answer:
7
Step-by-step explanation:
if h(x)=4 .. that would mean to plug 4 in as x
therefore .. 3(4)-5
3×4=12
12-5=7
If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:
(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.
Answer:
-22
Step-by-step explanation:
-10+(-2)6
(-2)6= -12
-10+(-12)= -22
hope i helped :)
