Answer:

D. 8x³ + 4x⁷ - 3x³ + 3x² - 2x + 9

Step-by-step explanation:

(8x⁸ - 9x³ + 3x² + 9) + (4x⁷ + 6x³ - 2x)

Apply distributive property to eliminate parentheses

8x⁸ - 9x³ + 3x² + 9 + 4x⁷ + 6x³ - 2x

Collect like terms

8x⁸ + 4x⁷ - 9x³ + 6x³ + 3x² - 2x + 9

8x³ + 4x⁷ - 3x³ + 3x² - 2x + 9

Ivan

Kyle purchased a 20 lb. pumpkin for $5.95.

Cost per lb of pumpkin for Kyle = 5.95/ 12 = $0.496.

Elizabeth purchased a 15 lb. pumpkin for $5.00.

Cost per lb of pumpkin for Elizabeth = 5.00/15 = $0.333.

Elijah purchased an 8 oz. pumpkin for $ 0.16.

16 oz = 1 lb

8 oz = 0.5 lb.

Cost per lb of pumpkin for Elijah = 0.16/ 0.5 = $ 0.32.

<h3>Cost per lb of pumpkin for Elijah is $ 0.32 is the lowest price per lb of pumpkin .</h3><h3>Cost per lb of pumpkin for Kyle is $ $0.496 is the highest price per lb of pumpkin .</h3><h3>Therefore, Elijah got the best deal and Kyle got the worst deal.</h3>

Indicate a general rule for the nh term of this sequence.<br> 12a, 15a, 18a, 21a, 24a,...
adelina 88 [10]

Answer:

The general rule for the nth term of this sequence will be:

a_n=3na+9a

Step-by-step explanation:

Given the sequence

12a, 15a, 18a, 21a, 24a,...

An arithmetic sequence has a constant difference 'd' and is defined by  

a_n=a_1+\left(n-1\right)d

Here,

a₁ = 12a

computing the differences of all the adjacent terms

d = 15a-12a = 3a, d = 18a-15a=3a, d=21a-18a=3a, d=24a-21a=3a

using the nth term formula

a_n=a_1+\left(n-1\right)d

substituting a₁ = 12a, d = 3a

a_n=12a+\left(n-1\right)3a

     =12a+3na-3a

     =3na+9a

Therefore, the general rule for the nth term of this sequence will be:

a_n=3na+9a
