Answer:
11x+7
Step-by-step explanation:
This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.
Answer:
Step-by-step explanation:
2 options
8,5,17 and 3,4,5
We know that
[area of the rectangular piece of cardboard]=20*9-----> 180 in²
[area rectangular pictures]=3*[7*4]-----> 84 in²
[area of the cardboard that is not covered by pictures]=180-84----> 96 in²
the answer is
The area of the cardboard that is not covered by pictures is 96 in²
Since the surface area of a prism is
A = 2lw + 2lh + 2wh
then the surface of the 1/3 scale key chain will be:
A = 2( l / 3 )( w / 3 ) + 2 ( l / 3 )( h / 3 ) + 2( w / 3 )( h / 3)
A = (2/9) ( lw ) + ( 2 / 9 ) ( lh ) + ( 2/9 ) ( wh)
A = ( 1 / 9 ) ( lw + 2lh + 2wh)
so the ratio <span>of the key chain to the book is 1/9</span>
