Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>
First. y=2x
second d is correct
third is a
Ok, so we know that the product of means something added, and we are given that eleven and a number are less than 53. So the equation is 11+X<53.
14 apples because altogether the ratio adds up to 7 and 49/7=7 so we could rewrite the ratio as 2x:5x so x=7. there for 2x ,the number of apples is 14
