Answer:

a: The answer is 36 units squared

b: You would lose four square units

Step-by-step explanation:

a: You can count the pieces showing, but you also have to add the amount you cannot see, which would give you a total of 36 units squared (since it doesn't say what each unit is represented by

b: The bottom pieces that originally were not showing would now be showing, but you would lose the ones above it. These cancel out from each other. There are 4 other sides that are now no longer showing since the others that are still showing still were anyways, so there are 4 units squared missing from the surface area when you remove the top two blocks.

Factor the expression using distributive property: 72b + 45

ANTONII [103]

The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!

Hope this helped! :D

If the original pair of a pair of shoes is $80 but a sign above the shoes reads “ Sale - 20% discount”, then what price would a

solong [7]

Answer:

A. 64

Step-by-step explanation:

The shoes are 80 dollars. We get a 20% discount

Discount = 80*20%

= 80*.20

=16

The sales price = original price less the discount

= 80 -16

= 64

• Puzzle refer to the above attachment .

dem82 [27]

The solution to this puzzle is 10+3 = 13

<h3>How to solve the puzzle</h3>

To solve this the values at the top of the star were gotten by the addition of two values inside the stars.

3 + 12 = 15
12 + 4 = 16
4 + 2 = 6
2 + 10 = 12
10 + 3 = 13

Therefore the answer to this question is 13.

Another way of getting the value is by adding 15 + 16 = 31

12 + 6 = 18

31-18 = 13
