-9
Step-by-step explanation:
I just took the same test
126 + 144 + 112= 382
Surface Area= 382 units squared
Answer:
6x² + 36x + 22
Step-by-step explanation:
2 faces (x + 3) by (x + 7), area of both these faces 2(x+3)*(x + 7)
2 faces (x + 3) by (x - 1), area of both these faces 2(x+3)*(x - 1)
2 faces (x -1 ) by (x + 7), area of both these faces 2(x-1)*(x + 7)
Whole surface area is
2(x+3)*(x + 7) + 2(x+3)*(x - 1) + 2(x-1)*(x + 7) =
=2(x² + 3x +7x +21) + 2(x² +3x -x - 3) + 2(x² - x +7x -7)=
=2x² <em>+ 20x </em>+42 + 2x² <em>+ 4x</em> - 6 + 2x² <em>+ 12x</em> -14 =
= 6x² + 36x + 22
Answer is 1/2.
Explanation:
We can divide 1 pizza up into 4 x 1/4.
So, 2 pizzas would mean 8 x 1/4.
However, if there is only 2 x 1/4, that would mean that it is half of 1 pizza. So,
2 x 1/4 = 1/4
I’m not very sure tho
