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

katrin [286]

Answer:

A) no real solutions

Step-by-step explanation:

No real solution. in order to x+1 by itself you must square root both sides. that would mean square rooting -5 which creates an imaginary number. so there are no real solutions. Also cause even if x was a negative, when you'd square it, you'll always get a positive.

0.70 * 8 = 5.6 grams <==

10 grams reduced by 40%.....so it contains 60%
60% of 10 =
0.60 * 10 = 
6 grams <==

so brand A, the 8 grams reduced by 30%, now has less fat <==
