Answer:
Answer: binomial
Step-by-step explanation:
Two different terms separated by a plus or minus term defines a binomial. You have a binomial.
1/2x is one of the terms.
the minus sign comes next
the 7 is the second term.
You would have to have common demoniators to add.
8/10 can be turn into 80/100 by multiplying the denominator and nominator by ten
75/100+80/100, you add the nominators ONLY, dont change the denominator.
75+80=155
so your answer would be 155/100
If x+2 is a factor of x^3+6x^2+kx+10, then if we replace x by -2 in the polynomial x^3-6x^2+kx+10, we must get zero:
x=-2→(-2)^3-6(-2)^2+k(-2)+10=0→
-8-6(4)-2k+10=0→
-8-24-2k+10=0
-2k-22=0
Solving for k. Adding 22 both sides of the equation:
-2k-22+22=0+22
-2k=22
Dividing both sides of the equation by -2:
-2k/(-2)=22/(-2)
k=-11
Answer: k = - 11
Answer:
x = 11
Step-by-step explanation:
2(x - 5) = 12 ← divide both sides by 2
x - 5 = 6 ( add 5 to both sides )
x = 11
