Step-by-step explanation:
√7*12
7*12=84
√84=9.16
(x-1)(x+2)(x+3)
This is how you would factor it out.
The correct answer is D.
the total calorie intake mark wants is 510.
He takes 30 for side dish (30s) and 45 for entree (45e)
therefore 30s + 45e = 510
now that you have an equation, judging by the choice of answers given... you have to make s the subject of formula
30s + 45 e can be factorised to 15(2s+3e) = 510
divide 510 / 15 = 34
now we have 2s + 3e = 34
hence 2s = 34 - 3e
didvide by 2 to make s 'free'
therfore you'll get s = 17-(3/2)e
Hope this helps! :)
