Not sure about the others but
b) 8,192
the pattern is multiplying by 8 each time for b
The area of the actual castle would be 388,800 sq. ft.
We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.
So...
180 x 4 = 720
180 x 3 = 540
If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.
720 x 540 = 388,800
Hope this helped! :D
The more expensive plan is the 3 year plan. He should expect to pay 306 a per month with would be 3682 (if I’m right) sorry about the other person I reported their answer
2x+3y=5
-3x+2y=-14
3( 2x+3y=5)
2 (-3x+2y=-14)
--------------------
13y=-13 ⇒y=-13/13=-1
2( 2x+3y=5)
-3(-3x+2y=-14)
---------------------
13x = 52 ⇒x=52/13=4
Answer: x=4; y=-1
To check:
2x+3y=5
2*4+3*(-1)=8-3=5
-3x+2y=-14
-3*4+2*-1=-12-2=-14
