Kinda like completing the square
if you have
ax^2+bx+c
a=1 for ease
take b and halve it then square that
then make c= that
x^2+2x+c
a=1 good
b=2
2/2=1
1^2=1
x^2+2x+1
(x+1)^2
the number 1 should be added

Answer:
844844844844/1
Step-by-step explanation:
So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:
Now, in this situation we can make use the elimination method by converting 3n to -27n.
Add both equations:
So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:
So one order of nachos cost $1.40.
SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7
5=H
