<span>The expressions that cannot be factored using integral coefficients and integral constants is the below:
</span>b. 2x2 + x + 4
d. x2 - 2x - 4
For a. 25x2 - 40x + 16 the factors are (5x – 4) (5x – 4)
For c. 6x2 - 2x - 20 the factors are (2x - 4) (3x + 5)
The total number of student can be solve by dividing the
partial student by its percentage of the overall student. Since there are 180
students in the band and it represnts 9% of the total students of the scool. So
the number of studetns are 180/0.09 = 2000 students
if you multiply 10.4x5x8 it equals 416 millimeters
Answer:
A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
Answer:
V = (1/3)pi(r^2)h (the first one)
