15/64

Step-by-step explanation:

Given

Red, R : 3 marbles

Blue, B : 5 marbles

Total : 5+3=8 marbles

If first marble is returned

P(Red) = 3/8

P(Blue) = 5/8

P (Red then Blue) = 3/8 x 5/8 = 15/64

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
