Factor 4
4=1 times 4
2 times 2
they don't add to 2
set up equation
x+y=2
xy=4
first equation, subtract x from both sides
y=2-x
subsitute for y
x(2-x)=4
distribute
2x-x^2=4
add x^2
2x=x^2+4
subtract 2x
0=x^2-2x+4
use quadratic formula which is
if you have ax^2+bx+c=0 then
x=

so
1x^2-2x+4=0
a=1
b=-2
c=4
x=

x=

x=

we have

and that doesn't give a real solution
therefor there are no real solutions
but if you want to solve fully
x=

i=

x=

x=

x=

or x=

(those are the 2 numbers)
Answer:
First one is 15.Second one is 3
Step-by-step explanation:
1 inch:10 meters 150÷10:15 26÷2:13 6÷2:3
K or l will be 151 degrees.
j and m are equal to each other, giving you x=1, substitute this in to get j and m equal 29 degrees. k or L are opposite angles meaning they add up to 180 when added to j and m so j+l=180 or m+k=180
Answer:
18 cups of dried split peas. 16 quarts of water. 6 cups of chopped onions. 8 cups chopped celery. 16 pounds ham shank.
Step-by-step explanation:
Since that is a recipe for 8 people and 8 is a factor of 32, we can multiply the ingredient amounts by 4 (4 x 8 is 32).
2 1/4 c x 8 = 18 c.
2 qt x 8 = 16 qt.
3/4 c x 8 = 6 c.
1 c x 8 = 8 c.
2 lb x 8 = 16 lb.
