Factor the trinomial 6x^2+5x- 25

Mathematics
1 answer:
vovikov84 [41]3 years ago

Answer:

x = 5/3    or   x = -5/2

(3x-5) or (2x+5)

Step-by-step explanation:

Given in the question an equation

6x²+5x- 25

here a = 6

        b = 5

        c = -25

To solve the polynomial equation we will use quadratic equation

x = -b ±√(b²-4ac) / 2a

Plug values in the equation

-5±√(5²-4(6)(-25)) / 2(6)

-5±√(25 + 600) / 2(6)

-5±√(625) / 2(6)

-5± 25 / 2(6)

-5 + 25 / 2(6)  or -5 - 25 / 2(6)

x = 5/3    or   x = -5/2

1. Points A and B are to be mapped onto a number line according to two equations. The solution to the equation 2/3 A= -24 is the
OleMash [197]
<span>The solution to the equation 2/3 A= -24 is the coordinate of point A.

2/3 A = -24
A = -24 / 2/3
A = -24 * 3/2
A = -72/2
A = -36

The solution to the equation 20=-b/0.5 is the coordinate of point B

20 = -b/0.5
20 * 0.5 = -b
10 = -b
10/-1 = -b/-1
-10 = b

A = -36 and B = -10

The distance between the two letters is 26 units. </span>

Answer:

1a. 8

1b. AB & BC

1c. AC

2. \sqrt{52} miles

3. NO

Step-by-step explanation:

1a. AC is your hypotenuse which is C² and BC is B², so we plug it in the equation.

A²+6²=10²

A²+36=100

A²=64

A=\sqrt{64}

A=8

1b. Legs are the two shorter sides, AB & BC, which are 6 & 8 respectively.

1c. The hypotenuse is the longest side AC

2. Make lines that make the graph for a triangle with a line. My graph is linked below. Then counts the points, AC=6, BC=4, then use the pythagorean therom.

6²+4²=X²

36+16=52

\sqrt{52}=X

3. 15²+17²=19²

514=361

not possible

so it is not a right triangle

Jack bought four dozen eggs at $10 per dozen six eggs were broken what percent of his money goes to waste?
Maurinko [17]
One dozen eggs is 48 eggs. Altogether that costs 40 dollars. If six of the eggs were broken then the money wasted would be 5 dollars.

The reason that it is 5 dollars is becuase it takes 10 to buy 12 eggs, and half of that is 6. So divide both 12 and 10 (separately) and you get 5 dollars for 6 eggs.

To get the percent you must divide 5 by 40.

The answer comes out to about 12.5% or 0.125.

So in the end, 12.5% of the money was wasted due to the broken eggs.

Hope this helped!
