9-pack

Step-by-step explanation:

Price per roll for 4-pack = Pack price / Number of rolls in pack

= 2.25 / 4

= £0.56 (rounded off to nearest cent)

Price per roll for 9-pack = Pack price / Number of rolls in pack

= 4.50 / 9

= £0.50

From here, we can see the 9-pack is of better value.

solve for K
7K-6
2K+14

Answers

Vertically opposite angles are the same meaning u have to do:

7k-6=2k+14

U have to solve for k.

7k-6=2k+14 - using this equation

Minus 2k on both sides

5k-6=14

Add 6 on both sides

5k=20
Divide 5 on both sides

K=4 the answer is 4.

To double check substitute it into 7k-6 and 2k+14. They should be same values

7(4)-6=28-6=22
2(4)+14=8+14=22

So 4 is correct because when u substitute back into the equation it gives you the same value.

Hey there!

Answer :

x = -1 or x = -8 ✅

Explanation :

To solve this equation, you have to use the zero product property.

Ifa product of factors is zero, then at least one of its factors is zero.

Which means that either x + 1 = 0 or x + 8 = 0

⇒ x + 1 = 0

Subtract 1 from both sides :

⇒ x + 1 - 1 = 0 - 1

x = -1

OR

⇒x + 8 = 0

Subtract 8 from both sides :

⇒x + 8 - 8 = 0 - 8

x = -8

Therefore, x = -1 or x = -8.

Surface area is the area (one side multiplied by another) of every side of the storage box, added together.
I have labeled each unique pair of sides as a, b, and c. That is top and bottom, left and right side, and front and back side.

Volume is the length multiplied by the width multiplied by the height.

By doubling the width, you are doubling the size of the box in that given direction. You can prove this mathematically by making the width twice of what it was and finding volume again.
