Answer:

X = 1

Step-by-step explanation:

We Start with this:

5(x + 1) + 6(x + 2) = 7(x + 3)

Next, use the distributive property to open the parenthesis.

5x + 5 + 6x + 12 = 7x + 21

Next, Combine like terms.

11x + 17 = 7x + 21

Add 7x to both sides.

11x = 7x + 4

Subtract 7x from both sides.

4x = 4

Divide both sides by 4.

X = 1

Answer:

$5(x + 1) + 6(x + 2) = 7(x + 3) \\ 5x + 5 + 6x + 12 = 7x + 21 \\ 11x - 7x = 21 - 17 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1$

which of the three sets could not be the lengths of the sides of a triangle {6,10,12} {5,7,10} {4,4,9} {2,3,3}

Phoenix [80]

So for this, we will be applying the Triangle Inequality Theorem, which states that the sum of 2 sides must be greater than the third side for it to be a triangle. If any inequality turns out to be false, then the set cannot be a triangle.

$A+B>C\\A+C>B\\B+C>A$

<h2>First Option: {6, 10, 12}</h2>

Let A = 6, B = 10, and C = 12:

$6+10>12\\16>12\ \textsf{true}\\\\6+12>10\\18>10\ \textsf{true}\\\\12+10>6\\22>6\ \textsf{true}$

<h2>Second Option: {5, 7, 10}</h2>

Let A = 5, B = 7, and C = 10

$5+7>10\\12>10\ \textsf{true}\\\\5+10>7\\15>7\ \textsf{true}\\\\10+7>5\\17>5\ \textsf{true}$

<h2>Third Option: {4, 4, 9}</h2>

Let A = 4, B = 4, and C = 9

$4+4>9\\8>9\ \textsf{false}\\\\4+9>4\\13>4\ \textsf{true}\\\\4+9>4\\13>4\ \textsf{true}$

<h2>Fourth Option: {2, 3, 3}</h2>

Let A = 2, B = 3, and C = 3

$2+3>3\\5>3\ \textsf{true}\\\\2+3>3\\5>3\ \textsf{true}\\\\3+3>2\\6>2\ \textsf{true}$

<h2>Conclusion:</h2>

Since the third option had an inequality that was false, <u>the third option cannot be a triangle.</u>
