The correct answer is: [A]: " 2x³ + 7x² + 12x − 8 " .
______________________________________________________
Explanation:
__________________________________________
Given:
__________________________________________
" (x² + 4x + 8) (2x − 1) " ; Find the product:
↔ " (2x − 1) (x² + 4x + 8) " ;
__________________________________________
Note: " (a + b) (c + d + e) = ab + ad + ae + bc + bd + ae " .
__________________________________________
→ " (2x − 1) (x² + 4x + 8) =
(2x * x²) + (2x * 4x) + (2x *8) + (-1 * x²) + (-1 * 4x) + (-1 * 8) ;
= 2x³ + 8x² + 16x + (-1x²) + (-4x) + (-8) ;
= 2x³ + 8x² + 16x − x² − 4x − 8) ;
→ Combine the "like terms" :
+ 8x² − x² = + 7x² ;
+ 16x − 4x = + 12x ;
_______________________________________________________
And rewrite the expression:
_______________________________________________________
→ " 2x³ + 7x² + 12x − 8 " ;
→ which is: Answer choice: [A]: " 2x³ + 7x² + 12x − 8 " .

The answer is a. you can see this because 1/3+1/3 gives you 2/3 and 1+1 gives you 2. when you add these two numbers together, it gives you mikayla’s total number of miles at 2 2/3.
Answer:
$2200
Step-by-step explanation:
Given that Owen has $7000 to pay, with a $1000 deductible. This means that he has, left to pay, $6000.
Again, we're told that he has 20% Co pay for the procedure. Taking 20% of $6000, we have
20/100 * 6000 = $1200. This means be has $1200 to co pay for the procedure.
Adding this newly calculated $1200 with the previously set aside $1000, we have a total of $2200. This is the price Owen will pay from his part, as part of the surgery
Let's represent the smaller number by x and the larger number x+23
x+x+23=65 x+23=21+23=44 So the two numbers are 21 and 44
2x+23=65
2x+23-23=65-23
2x=42
2x/2=42/2
x=21
