<h3><u>√2</u> is the right answer.</h3>

B) \sqrt{11}  + 3 \sqrt{11}  = (1 + 3) \sqrt{11}  = 4 \sqrt{11}

<h3><u>4√11</u> is the right answer.</h3>

Answer:

A) \sqrt{2}

B) 4\sqrt{11}

Step-by-step explanation:

A) You can add these expression because they contain the same square root:

6\sqrt{2}  - 5\sqrt{2} = (6 - 5)\sqrt{2} =\sqrt{2}

B) Same as above:

\sqrt{11} + 3\sqrt{11} = (1 + 3)\sqrt{11} = 4\sqrt{11}

2x/9 +x/3 = 13/6, solve for x
saveliy_v [14]

Answer:

x = 3 9/10

Step-by-step explanation:

2x/9 +x/3 = 13/6

Get a common denominator on the left side

2x/9 + x/3 *3/3 = 13/6

2x/9 + 3x/9 = 13/6

5x/9 = 13/6

Multiply each side by 9/5 to isolate x

5x/9 *9/5 = 13/6 * 9/5

x = 117/30

Divide the top and bottom by 3

x = 39/10

x = 3 9/10

What is the equation that passes through the given point and has the given slope (-2, -1); m= -3
klemol [59]

Answer:

y = - 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (- 2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = - 3x - 7 ← equation of line

Find the value of x that makes the two triangles equal
Leona [35]

Answer:

5

Step-by-step explanation:

\triangle CDE \sim\triangle FGH...(given)

\therefore \frac{CD}{FG}=\frac{CE}{FH}...(csst)

\therefore \frac{4x}{28}=\frac{25}{35}

\therefore \frac{x}{7}=\frac{5}{7}

\therefore x=\frac{7\times 5}{7}

\therefore x=5
