3k(k+10)=0 factor show steps please

Mathematics
1 answer:
saul85 [17]4 years ago

Answer:

Simplifying

3k(k + 10) = 0

Reorder the terms:

3k(10 + k) = 0

(10 * 3k + k * 3k) = 0

(30k + 3k2) = 0

Solving

30k + 3k2 = 0

Solving for variable 'k'.

Factor out the Greatest Common Factor (GCF), '3k'.

3k(10 + k) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'k' equal to zero and attempt to solve:

Simplifying

k = 0

Solving

k = 0

Move all terms containing k to the left, all other terms to the right.

Simplifying

k = 0

Subproblem 2

Set the factor '(10 + k)' equal to zero and attempt to solve:

Simplifying

10 + k = 0

Solving

10 + k = 0

Move all terms containing k to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + k = 0 + -10

Combine like terms: 10 + -10 = 0

0 + k = 0 + -10

k = 0 + -10

Combine like terms: 0 + -10 = -10

k = -10

Simplifying

k = -10

Answer:

  31.243 units

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.

  Sin = Opposite/Hypotenuse

  sin(30°) = BE/100

  BE = 100·sin(30°)

Then ...

  Tan = Opposite/Adjacent

  tan(58°) = BE/x

  x = BE/tan(58°) = 100·sin(30°)/tan(58°)

  x ≈ 31.243 . . . . units

_____

<em>Comment on the figure</em>

The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.

Solve for x: 7-3x=-2/5x-69/5
san4es73 [151]

Answer:

x = 8

Step-by-step explanation:

Step 1: Simplify both sides.

7 - 3x = -2/5x - 69/5

7 + - 3x = -2/5x + -69/5

-3x + 7 = -2/5x + -69/5

Step 2: Add 2/5x to both sides.

-3x + 7 + 2/5x  = -2/5x + -69/5 + 2/5x

-13/5x + 7 = -69/5

Step 3: Subtract 7 from both sides.

-13/5x + 7 - 7 = -69/5 - 7

-13/5x = -104/5

Step 4: Multiply both sides by 5/(-13)

(5/-13) * (-13/5x) = (5/-13) * (-104/5)

x=8
