Answer:

C. 3x²+2x+18

Step-by-step explanation:

<u>Let's factorize the given quadratic polynomial:</u>

  • 24x² + 16x + 144 = 8(3x²+2x+18)

<u>As we see it has 2 factors: </u>

  • 8 <em>and </em>3x²+2x+18

<u>Choice C is correct:</u> 3x²+2x+18

snow_lady [41]

Answer:

a+b+c+d = -5\cdot b

Step-by-step explanation:

The given system of equations is now reduced:

1) a+b = c, b+c = d, c+d=a, b > 0 Given

2) a = c+d By 1)

3) (c+d)+b=c 2) in 1)

4) d = b + c By 1)

5) [c+(b+c)]+b = c 4) in 3)

6) 2\cdot b + 2\cdot c = c Algebra

7) c = -2\cdot b Algebra

8) d = -b 7) in 4)/Algebra

9) a = -3\cdot b 7) and 8) in 2)/Algebra

10) a+b+c+d = -5\cdot b 9), 1), 7) and 8)/Algebra/Result

Answer:

m = -2

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in values:

m = 54 - 58 / 2 - 0

m = -4 / 2

m = -2

<u>ANSWER</u>=<u>5.2</u>

<u />

<u>EXPLANATION</u>

This triangle shows a example of the Pythagorean Theorem, which means the equation is gonna be

a^2+b^2=c^2

The variables <u>a </u>and <u>b </u>are the straight sides of the triangle, while the variable <u>c </u> is the curved side on the triangle, or what we are trying to find in this question.

Firstly let’s take the two sides that already have a number shown, also known in the Pythagorean Theorem as sides <u>a </u>and <u>b</u>.

2^2+4.8^2=c^2

Now we want to square the two given numbers to get the equation

4+23.04=c^2

Now we add the two given numbers that we have now squared to get the equation

27.04=c^2

The final step will now be to take the number (27.04) and square root it, which should give you the answer, <u>5.2</u>
