Since only the first term has ax for coefficients the GCF cant be -3ax^5.
The GCF would be -3a
Factor -3a out of all the terms:
-3a(2x^7)-3a(-4a^5)-3a(a^4)
Now factor -3a out of the equation for the final answer:
-3a(2x^7-4a^5+a^4)
we are given

Firstly, we will simplify left side
and then we can solve for k
Left side is

we can arrange like terms



now, we can use property of exponent



now, we can equate it with right side
and we get

We can see that both sides have 30 , a and b
and they are equal
so, exponent of a must also be equal

now, we can solve for k

................Answer
Not. They are not similar they are regular I think so
10 of 1/6 (10 times 1/6) is 1 4/65 or 1 2/3 simplified. 5 of 1/3 (5 times 1/3) is
1 2/3
Answer:
x > -3
the third option
Step-by-step explanation:
the circle is not filled in so we can first rule out the 2nd and last option. then since the arrow is pointing towards the positive side we can say x is more than -3
