False

Step-by-step explanation:

please mark barinlyest

A rectangle is quadrilateral which has four right angles. A square is both a rhombus and rectangle. Therefore, a square is always rectangle. Hence, the given statement is true. Converse: A quadrilateral is square when a quadrilateral is rectangle. This is false statement. A rectangle is quadrilateral which has four right angles.

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
