Answer:
mB=12-x
Step-by-step explanation:
mA+mC+mB=180
9x-12+5x+24+mB=180
9x+5x-12+24+mB=180
14x+12+mB=180
14x+mB=180-12
14x+mB=168
x+mB=168÷14
x+mB=12
mB=12-x

For questions 3 & 4, name the applicable polynomial identity and use the identity to multiply each expression.
3. (2 + 8)(2 − 8)
4. ( + 33)2
Answer:
The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0
has solutions x = 2 and x = 3.
Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.
Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.
A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.
As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

2) Find m2FGH if m_FGB = 105°
and mZBGH = 54º.
Answer:
159°Step-by-step explanation:
Angle addition postulate:
∠FGB + ∠BGH = ∠FGHm∠FGH = 105° + 54° = 159°angle FGB = 105°
angle BGH = 54°
To Find:The measure of angle FGH.
Explanation:angle FGB + angle BGH = angle FGH
By putting the respected values, we get
105° + 54° = angle FGH
or, 159° = angle FGH
Answer:The measure of angle FGH is 159° .

use (x+a)(x+b)=x2+(a+b)x+ab find 101*102
Answer:
[tex]101 * 102 = 10302[/tex]
Step-by-step explanation:
Given
[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]
Required
Find 101 * 102
[tex]101 * 102 =[/tex]
Express as a sum of 100
[tex](100 + 1) * (100 + 2)[/tex]
Compare this to [tex](x + a)(x + b)[/tex]
We have that:
[tex]x = 100[/tex]
[tex]a = 1[/tex]
[tex]b = 2[/tex]
Recall that:
[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]
Substitute 100 for x, 1 for a and 2 for b
[tex](100 + 1) * (100 + 2) = 100^2 + (1 + 2) * 100 + 1 * 2[/tex]
[tex](100 + 1) * (100 + 2) = 100^2 + 3 * 100 + 2[/tex]
[tex](100 + 1) * (100 + 2) = 10000 + 300 + 2[/tex]
[tex](100 + 1) * (100 + 2) = 10302[/tex]
Hence:
[tex]101 * 102 = 10302[/tex]

a tree is sold based on the circumference of the tree. if a tree has the radius of 4+inches, then what is the circumference of the tree
Answer:
The circumference of the tree will be: 25.12 inches
Step-by-step explanation:
The radius of the tree = r = 4 inches
As the tree is sold based on the circumference of the tree.
The formula of the circumference = C = 2πr
= 2(3.14)(4) ∵ r = 4 inches
= 25.12 inches
Therefore, the circumference of the tree will be: 25.12 inches

Two numbers multiply to -24 and add up to -5
Answer:
-8 and 3
Step-by-step explanation:
The asked numbers are -8 and 3.
What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, two numbers multiply to -24 and add up to -5
Let the two numbers be x and y
x+y = -5...(i)
xy = -24
x = -24/y...(ii)
Put eq (ii) in eq (i)
-24/y + y = -5
-24 + y² = -5y
y²+5y-24 = 0
Factorizing,
y = 8 and 3
Taking y = 3, put it in eq(ii)
x = -24/3
x = -8
Hence, the asked numbers are -8 and 3.

Answer:
121cm −25πcm ≈42.46cm
Step-by-step explanation:
First, calculate the area of the whole figure, including the unshaded area.
(The area of a rectangle is the length times the width.)
Next, calculate the area of the inner figure.
π×5cm×5cm=25πcm

Answer:
80°
Step-by-step explanation:
alternate angles are equal
angles in a straight line add upto 180°
therefore angle ABC =80°
But it is alternate to the one at x.
Answer:
x = 80°
Step-by-step explanation:
∠CBD = ∠ABF
= 100°
(Vertically opposite angles are equal and AD and EH are parallel with CG cutting across both lines)
∠x = 180°-100°
= 80°
(∠ABF and ∠x are consecutive interior angles as they are within two parallel lines so they add up to 180°)

Answer:
-5v+3v = -2v
k-2-6+5k = 6k - 8
Step-by-step explanation:
For -5v+3v
-5 + 3 = -2
V is left so it's -2v
For k-2-6+5k
k + 5k - 2 - 6
6k - 2 - 6
6k - 8
1) -5v + 3v
= -2v
2) k - 2 - 6 + 5k
First take all like terms (everything with the same letters):
k + 5k = 6k
6k - 2 - 6
-2 - 6
= -8
6k - 8

-7.4 < -5.2
|-1.5| < 0
Answer: D.
Step-by-step explanation:
The last statement is false.
Answer:
1 is false.
Step-by-step explanation:
1. Look at the signs.
2. Look at the number itself. If you are dealing with a positive, you count up to get higher numbers. If you are dealing with a negative(a number with - at the beginning) you count up to get lower numbers.
3. Compare the decimal in the number to the decimal in the other number.
4. Look at the greater-than and less-than signs.
5. Use what you know about positive and negative numbers and decimals and apply that to the statement. If the statement makes sense, it is true. If the statement does not make sense, it is false.
