(y+6)^2-(y-2)^2 I got 16y+26 but it is wrong?

Mathematics
1 answer:
Gemiola [76]3 years ago
5 0

Answer:

16y + 32

Step-by-step explanation:

Expand each term.

(y+6)² - (y-2)²

= (y+6)(y+6) - (y-2)(y-2)

= y² + 12y + 36 - (y² - 4y + 4)

Subtract the second group by changing each term's signs

= y² + 12y + 36 - y² + 4y - 4

Collect like terms

= 16y + 32

HELLO. I NEED HELP ON A HANDFUL OF QUESTIONS. PLEASE HELP. ​
galben [10]

Question 7: $3945

78,900÷100×5= 3,945

or 789,00×0.05= $3,945

Question 8: I think it may be $675.46 ( but I'm not sure)

$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12

$1010÷12= $84.20

also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.

$938÷12=$78.20

and in order to find out her combined monthly payment we need to add them all together

$513.12+$84.16+$78.16= $675.46

Question 9: is False

Question 10: I don't know

Hope this helps

What time is 5 3/4 hours after 11:32 PM
Viktor [21]

Answer:

So the time is 5:17 a.m.

Explanation:

Note that:

11:32 pm is 28 minutes before midnight.

Adding the 534 hours will take the time into early morning.

So all we need to do to find the new time (am) is to subtract 28 minutes from 534 hours.

534→5 hours and 45 minutes

Subtracting the minutes:

45

28−− ← Subtract

17

So the time is 5:17 a.m.

Indicates an example of the associative property of multiplication.

(6 * 5) * 4 = 6 * (5 * 4)\\30 * 4 = 6 * 20\\120 = 120

Similarly, we observe the associative property of multiplication
