−a2 − 3b3 + c2 + 2b3 − c2 if a = 3, b = 2, and c = −3

Start by setting up your two sets of parenthses.

Inside, we have the terms that compose each binomial.

Since x² breaks down into x · x, we use an x in each binomial.

The second term is the factors of -12 that add to the coefficient

of the middle term but what is the coefficient of the middle term?

If there is nothing written there, it's understood to be 1.

So factors of -12 that add to -1 are 4 and -4.

So we have (x + 4)(x - 3) which is our answer.

Answer:

x = 4 , x = -3

Step-by-step explanation:

x^2 - x - 12 = ( x - 4) ( x + 3)

x - 4 = 0 or x + 3 = 0

x = 4 or x = -3

Answer:

Option C. 28

Step-by-step explanation:

From the question given,

m<HKM = 155°

m<JKL = (5x + 15)°

From the diagram,

m<HKM = m<JKL (since they are directly opposite)

Inputting the value of m<HKM and m<JKL into the above expression, we have:

m<HKM = m<JKL

m<HKM = 155°

m<JKL = (5x + 15)°

155 = 5x + 15

Collect like terms

155 – 15 = 5x

140 = 5x

Divide both side by 5

x = 140/5

x = 28

Therefore, the value of x is 28.

Answer:

44/100 will be reduced to 11/25

Step-by-step explanation:

Answer:

11/25

Step-by-step explanation:

First, we know 44% can be changed to 44/100, since 44 is 44% is 100.

Now, we can simplify 44/100:

44/100

= 22/50

= 11/25

So, 44% is equivalent to 11/25

Answer:

The answer is -14/25 or - 0.56

Answer:

BC = 1/2 AC

2m angle DBC = m angle ABC

Angle ABC is bisected by ray BD

m∠WUT = 38°

Step-by-step explanation:

For both questions, we use the Angle Bisector Theorem.

Question 1:

We know since ray DB bisects ABC, AB and BC are congruent. They are split into 2 equal parts. Therefore, we know that if we take half of mAC, we should get either mBC or mAB. Therefore, the 1st statement is correct.

Since it is ray DB bisecting ABC, it created 2 right angles. If angle DBC was bisected, it would create 2 new angles that were 45° each, so the 2nd statement is incorrect.

We know that line ABC is equal to 180°. So if we add m∠ABD and m∠DBC (they both are 90°, as denoted in the picture) together, we should get 180°. Also, since they are congruent angles, one angle multiplied twice would also be 180°. Therefore, the 3rd statement is correct.

The Angle Bisector Theorem doesn't state that the bisector and one segment would be congruent. The length of the bisector could be anything and is not marked congruent to the other segments. Therefore, the 4th statement is incorrect.

Since we see that there is a bisector DB bisecting line ABC, creating 2 congruent segments and angles, we know that the 5th statement is correct.

Question 2:

The Angle Bisector Theorem states that a bisector that bisects 2 angles will become 2 smaller but congruent angles. So,

Step 1: Find x

4x + 6 = 6x - 10

6 = 2x - 10

16 = 2x

x = 8

Step 2: Find m∠WUT

m∠WUT = 6x - 10

m∠WUT = 6(8) - 10

m∠WUT = 48 - 10

m∠WUT = 38°

Answer:

Step-by-step explanation:

First equation:  2x^2 + 6x = 0 factors into 2x(x + 3) = 0, so either x = 0 or x = -3.

Second equation:  x^2 + 9x + 14 = 0 factors into (x + 2)(x + 7) = 0.  Thus, either x = -2 or x = -7

Answer:

-2

Step-by-step explanation:

At first, you might think that -5 is bigger than -2 because 5 > 2, right? Actually, no, that's not how it works. The "rules" for numbers are flipped when you are dealing with negative numbers, so therefore, -2 is bigger. Basically, what I'm saying is that the smaller the number after the negative sign, the bigger the number is and vice versa.

Answer:

Not enough tables.

Step-by-step explanation:

Circumference is 2*pi*r

The diameter is 2 times the radius or 2r, if the table diameter is 180cm. All we need to do is multiply by pi (3.14159) to get the circumference.

180*pi = 556.48cm

If each guest needs 70cm then we divide the circumference by 70

556.48/70 = 8.08 but we cant have a portion of a person so we can fit 8 people per table.

18 tables with 8 at a table is 8 x 18 = 144

If 145 guests are attending then there aren't enough tables, you are 1 table short.

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

Explanation:

If we had x^2+2x + ___, then 1 must go in the blank so that we have x^2+2x+1 = (x+1)^2

So we must add 1 to both sides to complete the square for the x terms. To find this value '1' we take half of the x coefficient 2 to get 1, then square it to get 1^2 = 1.

We have

x^2+y^2 + 2x - 20y - 20 = 0

x^2+y^2 + 2x - 20y - 20 + 1 = 0 + 1

(x^2+2x+1) + y^2 - 20y - 20 = 1

(x^2+2x+1) + y^2 - 20y = 1 + 20

(x+1)^2 + y^2 - 20y = 21

After completing the square for the x terms. Repeat for the y terms. Take half of -20 to get -10, which squares to 100. Add this to both sides

(x+1)^2 + y^2 - 20y = 21

(x+1)^2 + y^2 - 20y + 100 = 21+100

(x+1)^2 + (y - 10)^2 = 121

The equation is in the form (x-h)^2 + (y-k)^2 = r^2 where

The center is (h, k) = (-1, 10). The radius is r = 11.

Answer:

6/21.

Step-by-step explanation:

let the rational number be 2x/7x.

2x + 4 / 7x - 2 = 10 /19

Cross multiply:

19(2x + 4) = 10(7x - 2)

38x + 76 = 70x - 20

96 = 70x - 38x

32x = 96

x = 3.

So the rational number is  2*3/ 7*3

Answer:

(A) It will be equal to -25

Step-by-step explanation:

Given a number between -35 and -15.

To find:

A statement always true about the number.

(A) It will be equal to -25.

(B)It will be less than -20.

(c) It will be more than -10.

(D)It will be less than -10

Solution:

First of all, let us represent the given numbers on number line.

Please refer to the attached diagram for the number line representation of the numbers.

When we move towards left from 0, the numbers decrease.

Therefore, -15 is a value greater than -35.

-15 > -35

When we move towards right from 0, the numbers increase.

So, statement "A)It will be equal to -25" is true.

-25 will always be in between -15 and -35.

Option B:

Less than -20.

-40 is also lesser than -20 but is not in between -35 and -15.

So not true.

Option C:

More than -10.

-8 is also more than -10 but not in between -35 and -15.

So not true.

Option D:

Less than -10.

-11 is also lesser than -10 but is not in between -35 and -15.

So not true.

Answer: Hi!

To find the distance of the point from each axis, all we have to do is look at the x and the y coordinates of the points. If we wanted to find the distance that point P was from the x axis, we would look at our y - coordinate:

(x, y) = (3, 4) So, point P is 4 units away from the x -axis.

Now we need to look at the x - coordinate to find the distance that point P is from the y axis:

(x, y) = (3, 4) So, point P is 3 units away from the y - axis.

Answer: The maximum value is 35.94

Step-by-step explanation:

We have the function:

f(x) = -16*x^2 + 34*x + 20

This is a quadratic equation, and the first thing we can see is that the leading coefficient is smaller than zero, which means that the "arms" of the graph will go downwards, which means that the maximum of our function will be at the vertex.

First, we know that the vertex of a quadratic function is when f'(x) = 0.

f'(x) = 2*(-16*x) + 34 = 0.

x = -34/(-2*16) = 34/32 = 17/16.

Now we evaluate our function in the point x = 17/16.

f(17/16) = -16*(17/16)^2 + 32*(17/16) + 20 = 35.94

The maximum value is 35.94

Using the vertex, it is found that the maximum value of the function is of 36.

The function is given by:

[tex]f(x) = -16x^2 + 32x + 20[/tex]

Which is a quadratic function with coefficients [tex]a = -16, b = 32, c = 20[/tex].

The maximum value of a quadratic function with [tex]a < 0[/tex] is at the vertex, in which the value is:

[tex]f_{MAX} = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}[/tex]

Hence, in this problem:

[tex]f_{MAX} = -\frac{(32)^2 - 4(-16)(20)}{4(-16)} = 36[/tex]

The maximum value of the function is of 36.
