4)

12/16=21/b

multiply both sides by b
(12/16)b=21

now multiple both sides by (16/12)
b = 21 (16/12) =28

5)
rate is distance / time or time/distance

train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p

answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km

looking at choice A.. 1.5hr/270km=5hr/k km

the units don't match for choice C so the

right answer is A

6)

1.5/270=5/k

multiply both sides by k
(1.5/270)k=21

now multiple both sides by (270/1.5)
k = (270/1.5)21= 900

7) 75 points per 6 game

75 points / 6 games

75/6=P/20

multiply both sides by 20
(75/6)20=P

P=250

Not sure how to do this problem
myrzilka [38]
First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.

(x - 1) = 0

That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.

Multiply all the factors together.

(x-1)(x-4)(x+3)=0

Now FOIL.

(x^2-5x+4)(x+3)

x^3-2x^2-11x+12

Give two examples of line segments that will make a triangle ?
77julia77 [94]

Answer:

If the length of any one side is greater than the sum of the length of the other two, the line segments cannot be used to create a triangle. It is possible to create a triangle using 3 line segments if the sum of the lengths of any two line segments is greater than the length of the third.
