The question is about types and number of soultions so you must use b^2-4ac which is the experssion under the root in the quadratic formula
so
if
b^2-4ac=0 then there is one real soultion
if
b^2-4ac<0 then there are two imaginary soultions that differ in the sign between them
if
b^2-4ac>0 then there are two real soultions
so a polynomial is written in the form
ax^2+bx+c=0
so a=-4
b=-4
c=-1
so b^2-4ac=16-16=0
so one real soultion is the answer you are looking
type:real
number:1
Answer:
the total number of calories in the jar of peanut butter, x, and the total number of calories in the jar of jelly, y
The difference in the total number of calories in a jar of peanut butter and a jar of jelly is 3,545
Now we use total calories ,which was 2/23 of the jar of peanut butter and 2/33 of the jar of jelly
x minus y = 3545 and StartFraction 2 Over 23 EndFraction x + StartFraction 2 Over 33 EndFraction y = 430
Step-by-step explanation:
THANK U THEY KEEP COMMENTING THAT ON MY POST
2(2x+1)= (2 x 2x) + (2 x 1) = 4x + 2
