Answer:
There are NO real solutions to this equation as per the study of its discriminant.
Step-by-step explanation:
In order to answer the question, one needs to examine the "discriminant" associated with this quadratic equation.
Recall that the discriminant of a quadratic equation of the form:
is given by:
in our case :
Then the discriminant becomes:
The discriminant is then a negative number, which means that there are NO real solutions (its solutions must involve imaginary numbers)
Answer:
43.98 feet
Step-by-step explanation:
Answer:
7.5 < x < 8
Step-by-step explanation:
since the domain of a function is the value it can take as an argument except 0, then f(x) = 7.7.
The answer will be -3p -4
(A) Ar(Rectangle)=l*w
= x^2-6x-27=l(x-9)
= x^2-9x+3x-27
= x(x-9)+3(x-9)
= (x+3)(x-9)
Width= (x-9)
Length= (x+3)
Thus, the length of the Rectangle is (x+3) units.
(B) (L+3)*(W+3)=?
= [(x+3)+3]*[(x-9)+3]
= (x+9)*(x-6)
= x^2-6x+9x-54
= x^2+3x-54
Thus, the area of the larger triangle is x^2+3x-54 units
