A hole the size of a photograph is cut from a red piece of paper to use in a picture frame.
mario62 [17]

Answer:

D. 47 square units

Step-by-step explanation:

The area of the piece of red paper after the hole for the photograph has been cut is the difference between the area of large square and are of small square.

<u>Area of large square:</u>

The length of the side of large square is

EF=|-4-4|=8\ units

Area of large square =8^2=64\ un^2.

<u>Area of small square:</u>

The length of the side of large square is

AB=\sqrt{(-3-(-2))^2+(-2-2)^2}=\sqrt{(-1)^2+(-4)^2}=\sqrt{1+16}=\sqrt{17}\ units

Area of small square =\sqrt{17}^2=17\ un^2.

<u>Difference:</u>

64 \ un^2-17\ un^2=47\ un^2

4 • (6 – 4) 2 ÷ 2
Dmitry_Shevchenko [17]

Answer:

Cary is wrong

Step-by-step explanation:

4* (6-4)= 4* 2=8

I think it is saying (8*2) divided by to, which in that case is 8,

but if it is asking 8 (2/2) then that would also be 8 I believe. I really hope this is correct and you have a great day :)
