4 0

If the zeros are x=-4 and -6, then the factors are:

(x+4)(x+6) which expanded is:

f(x)=x^2+10x+24

Two trains leave the station at the same time one heading east and one heading west the eastbound train travels 80 miles per hou

k0ka [10]

100*2.2=220
80*2=176
220+176=396

So the two trains will take 2.2 hours so that they are 396 miles apart.

The diagram shows a circle with center C, a diameter RS, and an inscribed triangle RST.

snow_tiger [21]

Answer:

x = 26

Step-by-step explanation:

m<RTS = 4x - 14 (given)

Based on the inscribed angle theorem, the measure of the inscribed angle in a semicircle = right angle (90°)

Therefore,

4x - 14 = 90

4x - 14 + 14 = 90 + 14 (addition property of equality)

4x = 104

4x/4 = 104/4

x = 26
