28-7x
Step-by-step explanation:
To write the expression without grouping symbols, multiply the 7 into both terms using the distributive property.
7*4 - 7^x
28-7x

Step-by-step explanation:
By Factor Theorem, (x + 3) is a factor of H(x) if and only if H(-3) = 0.
3(-3)³ - 2(-3)² + (-3)k - 3 = 0
-81 - 18 - 3k - 3 = 0
3k = -102
k = -34.
