Answer:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Step-by-step explanation:
Answer:$24 on 2016
Step-by-step explanation:
2012 = $30
2015 = $25.50
30.00-25.50=4.50
$4.50
so,3 years different, so that 4.50/3 years = $ 1.50
Answer:
y+x=1
y-x=1
Step-by-step explanation:
Well If x is 0, its pretty straight forward.
1+0=1
1-0=1
lol hope this helps
This form (x+b)²+c is a vertex form that can be found by completing square for the equation <span>x²+440x+440².
To complete square we will need to use formula a² +2ab + b² = (a+b)²
</span> x²+440x+440²,
<span>x² +2*220²x +220² -220² +440² (we added </span>220² -220², so nothing really changed here).
x² +2*220²x +220² -220² +440² ( here , bold part can be rewritten as (x+220)²)
(x+220)² -220² +440² (calculating bold part)<span>
</span>(x+220)² -220² +440² = (x+220)² + 145200
Now we have x²+440x+440², in the form that we need
x²+440x+440² = (x+220)² + 145200
(x+b)²+c = (x+220)² + 145200,
b=220,
c= 145200
So,
c/b = 145200/220 = 660
c/b = 660/1 (if you need it in a fraction form) or 660.
-4+2=-2
and that equation is equal to f(x)
so plug in the x
f(-1)=-2
2 times -1 = -2
