Answer:

  x = 10√3

Step-by-step explanation:

The Pythagorean theorem tells you ...

  FB^2 = BC^2 +CF^2

  FA^2 = FB^2 +BA^2

Substituting for FB^2, we have ...

  FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2

  FA^2 = 3x^2

  FA = x√3 = 30 . . . . take the square root and substitute for FA

  x = 30/√3

  x = 10√3

Answer:

x2 + 5x-6

Step-by-step explanation

Consider the form

c

. Find a pair of integers whose product is

c

and whose sum is

b

. In this case, whose product is

−

6

and whose sum is

5

.

−

1

,

6

Write the factored form using these integers.

Answer:

First, you have to add 11 on both sides, so the answer is A

Answer:

3

Step-by-step explanation:

y-3 = 3x+12

y = 3x +15

so slope = 3 ( number next to the x)

Step 1: Find the sum of the interior angles

Use this formula: 180 x (n - 2)

n is the number of sides of the polygon

Work:

180 x (4 - 2)

180 x 2

360

Step 2: Find the angle right above the 94 degree angle

The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.

Work:

360 - 94

266

Step 3: Set up an equation to find the missing angle p

We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.

360 = 12 + 75 + 266 + p

360 = 353 + p

p = 7 degrees

Does this answer make sense?

Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.

Hope this helps!! :)

Answer: A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.

Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Note that 24 hours = 1 day

Answer: 39

Step-by-step explanation:

D. 39

you use the pythagorean theorem which is [tex]a^{2}+b^{2} = c^{2}[/tex]

if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).

so your equation will look like this:  

         [tex]15^{2} + 36^{2} =c^{2}[/tex]

1. [tex]15^{2} + 36^{2} =c^{2}.[/tex]      (solve for [tex]15^{2} and 36 ^{2}[/tex])

2. C= 225+1296      (add)

3.  C= 1521               (find the square root of 1521)

4. [tex]\sqrt{1521} = 39[/tex]

Therefore, 39 is your answer

Hope this helps!

===================================================

Explanation:

The combination of angle x and the 93 degree angle forms x+93. This obtuse angle is congruent to 130 because these two angles are alternate interior angles and because line L is parallel to line M.

So,

x+93 = 130

x+93-93 = 130-93 .... subtracting 93 from both sides

x = 37

The value of x is 1/2y+3/2

Answer:

y = 2x - 3

Step-by-step explanation:

8 + 2y - 5x + y = x - 1

3y = 6x - 9

y = 2x - 3

slope is 2, y-intercept is -3

Answer:

270 degrees

Step-by-step explanation:

Take note that to convert Pi to Radians you need to use the formula of

180 degrees = Pi radians

Therefore if you have 180 degrees multiplied by 9 Pi over 6 you get the degree measurement of 270

I believe, The answer to your question is:

B. 270°

Answer:

$656.77 is left

Step-by-step explanation:

-$1,500 budget

Spends: $225.30, $482.25, 135.68.

Now subtract all these values with 1,500.

1500 - 482.25 - 225.30 - 135.68 = 656.77

Answer:

(5,-6) I think

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

(1, 2/3) (-1, -1) are the points. use the slope formula to find the slope y2-y1/x2-x1

(-1 - 2/3) / (-1 -1) (answer both sides of the division side)

-5/3 / -2  (divide)

slope = 5/6  (the slope)

plug in values you know into point-slope form (y -y1) = m(x-x1)

y - (-1) = 5/6 (x - (-1) (i chose the easier point to plug in. two neg. make a pos. )

y +1 = 5/6 (x +1)  (use the distributive property)

y +1 = 5/6x+5/6  (subtract 1 from both sides)

y = 5/6x - 1/6  or B (this is the equation)

Answer:

[tex]b+1\\b+2\\b+(b+1)+(b+2)=24[/tex]

Step-by-step explanation:

If [tex]b[/tex] represents the youngest brother's age, the second oldest brother's age can be written as [tex]b+1[/tex] and the third can be written as [tex]b+2[/tex], since they're all consecutive.

The sum of all their ages is then [tex]b+(b+1)+(b+2)[/tex] which is equal to [tex]24[/tex], as given.

Answer:

The scale factor of the dilation is 3 ⇒ A

Step-by-step explanation:

In the given figure

∵ EFGH is a polygon

∵ E = (-2, 1), H = (-2, -1)

∵ EH is a vertical side

→ By using the 2nd rule above

∴ The length of EH = 1 - (-1) = 1 + 1

∴ The length of EH = 2

∵ E'F'G'H' is its image after dilation by scale factor k

∵ E' = (-2, 5), and H' = (-2, -1)

∵ E'H' is a vertical side

∴ The length of E'H' = 5 - (-1) = 5 + 1

∴ The length of E'H' = 6

→ By using the 1st rule above

∴  [tex]\frac{E'H'}{EH}[/tex] =  [tex]\frac{E'F'}{EF}[/tex] =  [tex]\frac{H'G'}{HG}[/tex] =  [tex]\frac{F'G'}{FG}[/tex] = k

∵  [tex]\frac{E'H'}{EH}[/tex] = k

∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]

∴  [tex]\frac{E'H'}{EH}[/tex] = 3

∴ k = 3

∴ The scale factor of the dilation is 3
