<h2>Answer with Step-by-step explanation:</h2>

If a polynomial has roots a and b

Then, equation of polynomial can be given by:

(x-a)(x-b)= x²-(a+b)x+ab

Here, we are given roots of polynomial to be 1 and -4

i.e. a=1 and b= -4

Polynomial equation=x²- (1+(-4))x+1(-4)

                                  = x² - (1-4)x - 4

                                  = x² + 3x - 4

Hence, A polynomial equation with integer coefficients that has roots x=1 and  x= -4 is:

x² + 3x - 4

Part D<br> What is the measurement of angle C?
NeX [460]

Step-by-step explanation:

I think we are missing some information (angle F or B or a side length would be great).

but just the right angles are not enough to calculate specific numbers. they would depend on the angle F or e.g. the side length of AB.

without any further information F and AB can be freely changed without changing the known facts, but it changes also C, B, G

so, all I can say is C = 180 - B.

and that G = B.

How many cm in 1.5 km
nignag [31]

Answer:

1.5 Kilometers and 150000 Centimeters

Step-by-step explanation:

5 × 10 -5 kilometers in 1 1 / 2 centimeters. To convert any value in centimeters to kilometers, just multiply the value in centimeters by the conversion factor 1 / 100000 . So, 1.5 centimeters times 1 / 100000 is equal to 1.5 × 10 -5 kilometers.

I hope this helps!

Suppose you choose a marble from a bag containing 6 red marbles , 2 white marbles and 5 blue marbles you return the first marble
algol [13]

Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

                             = 6/13 * 5/13 = 30/169
