Answer:
174 packages of t-shirts PLEASE GIVE BRAINLIEST
Step-by-step explanation:
139 x 5 = 695 t-shirts are needed
695 ÷ 4 = 173.75
Since you have to purchase whole packages of t-shirts you will need to buy 174 packages of t-shirts. 174 x 4 = 696 t-shirts
174 packages
Answer:
4x - 12
Step-by-step explanation:
Expand 8 - 4(-x + 5) as follows:
8 + 4x - 20
4x - 12 (First answer is the correct one)
Answer:
f(x) has two imaginary roots and one real root.
Step-by-step explanation:
Complex roots:
I a complex number 
is a root of a polynomial, it's conjugate 
is also a root.
One root of a third degree polynomial function f(x) is -5 + 2i.
This means that -5 - 2i is another root of the polynomial, and thus, 2 of the roots are complex.
Third degree, so it has three roots, which means that the third root is real(not possible to have a complex root without it's conjugate), and thus, the correct answer is:
f(x) has two imaginary roots and one real root.
If a polynomial has more than one variable, then the degree of that monomial is the sum of the exponents of those variables. In this polynomial, 24xyz, the degree is 3 because the sum of degrees of x, y and z is 1 + 1 + 1 = 3.
