STEPS :

(8m + 7) ^ 2  
Apply distributing rule : (a + b)^2 = a^2 + 2ab + b^2

= (8m)^2 + 2 ⋅ 8m <span>⋅ 7 + 7^2
</span>   (8m)^2 = 64m^2
   2 ⋅ 8m <span>⋅ 7 = 112m
</span>   7^2 = 49

= 64m^2 + 112m + 49

Hope this helps :)

Solve for x. Express the answer in simplest form. <br>2/1 = 8x - 2/ 9
oksano4ka [1.4K]
2=8x-2/9
add 2/9 to both sides
2 and 2/9=8x
2=18/9
2 and 2/9=18/9+2/9=20/9
20/9=8x
multiply both sides by 9
20=72x
divide boht isdes by 72
20/72=x=5/18

Not sure if this is very clear
Patty = 45.8%
Bun = 20.8%
Cheese = 8.3%
Sauce = 12.5%
Pickles = 4.2%
Veggies = 8.3%

EXPLANATION :

The equation to find a percentage is part(the broken down calories) over whole ( the total calories) is equal to % which we replace with x (since we’re trying to find the %) over 100 because all percents are out of 100. So for simple terms, p/w = %/100.
What I did was put 550/1200 = x/100, cross multiply, leaving you with 1200x=55000, then divide 55000/1200, giving you 45.8.
