Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add to
both sides of the equation to complete the square? Pleaseee Help

Answers

Answer 1

Answer:

Richie should add the number 36 to both sides.

Step-by-step explanation:

To complete the square, you need to divide b by 2, square it, then add it to both sides. In this case, you'd do this:

12/2=6

6^2=36

A bag contains 14 blue marbles, 10 red marbles, and 6 yellow marbles.
If Henna randomly draws a marble from the bag (and puts it back) 25 times, how many
times should she expect to pull a yellow marble?

Answers

Answer:

5

Step-by-step explanation:

14+10+6= 30 (6/30 = 0.2) 0.2 x 25=5

75=(4x-25)

What is the value of x?

Answers

Answer:

x = 25

Step-by-step explanation:

75 = (4x - 25)

Since there are no numbers outside of the parentheses, we can remove them.

75 = 4x - 25

Now we can see that we can add 25 to both sides.

100 = 4x

Divide both sides by 4 to isolate x.

25 = x

Check by plugging in the value into the original equation.

75 = 4(25) - 25

75 = 100 - 25

75 = 75

Your answer is correct.

Hope this helps!

Answers

Step-by-step explanation:

As we know corresponding angles are equal so

6x - 100° = 2x + 4° < being corresponding angles>

6x - 2x = 100 ° + 4°

4x = 104°

x = 104° / 4

x = 26°

What is a point-slope equation of the line with slope -12 that goes through the point (5,3)?

Answers

Answer:

D. y - 3 = - 12 ( x - 5)

Step-by-step explanation:

Given

Slope (m) = - 12

Point = ( 5 , 3 ) = ( x1 , y1)

Now

Writing in point-slope equation we get

y - y1 = m( x - x1)

y - 3 = - 12 ( x - 5 )

4.) A store is having a sale in which all items are marked 30% off.

priced p dollars after a markdown of 30%?
a.) s=0.3p
b.) s=0.7p
c.) p=0.35
d.) p=0.75

Answers

Answer:

0.70p

Step-by-step explanation:

"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%).  Next, find the decimal equivalent of 70%:

It is 0.70.  Finally, multiply the price p by 0.70:  0.70p (Answer b)

Answer:

[tex]\sqrt{149}[/tex]

Step-by-step explanation:

The third side of a triangle can be any value in the range of -

1 ≤ a < 17.

What is a triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane

Given are two sides of a triangle as b = 7m and c = 10m.

The sum of two sides of a triangle is always greater than the third side. Mathematically -

a < {b + c}

a < {7 + 10}

a < 17

a ∈ [1, 16]

Therefore, the third side of a triangle can be any value in the range of -

1 ≤ a < 17.
