1×100000+2×10000+9×1000+9×100+8×10+2×1
=100000+20000+9000+900+80+2
Answer:
(a-1) *(a^2 +a-1) (a+2)
Step-by-step explanation:
a^4+2a^3-a-2
Lets factor by grouping
a^4-a + 2a^3-2
Factor out an a from the first group and a 2 from the second group
a(a^3 -1) +2(a^3-1)
Factor out (a^3-1)
(a^3-1)(a+2)
We need to recognize that a^3-1 is the difference of cubes
(x^3-y^3) = (x-y) (x^2+xy+y^2)
Let x=a and y=1
(a-1) *(a^2 +a-1) (a+2)
5/8
explanation:
if we turn the first option into an improper fraction: we get 1 3/4, so it’s not the first answer. for the second answer choice, we can convert 3/4 into the 8ths by multiplying both parts of the fraction by 2 to get 6/8. Since 7/8 is greater than 6/8, it’s not the second choice either. Knowing that 3/4 is the same as 6/8, 5/8 is less then 6/8 because 5 is less than 6. So, 5/8 is between 3/4 and 1. hope this helped!!
Answer:
Checkout the image below the explanation.
Step-by-step explanation:
1. First, let's solve the inequality.
Step 1: Simplify both sides of the inequality.
Step 2: Subtract 2 from both sides.
Step 3: Divide both sides by -6 and flip the sign.
2. Now that we solved the inequality and got x > -1, that means that all values of x are more than -1. It can be represented on the number-line as this:
