(m-21) (m+1)there I thinks it's right unless I messed up my work

Answer:

[tex](m - 21)(m + 1)[/tex]

Step-by-step explanation:

[tex]m^{2} - 20m - 21[/tex]

Lets split the middle term.

[tex]=> m^{2} - 21m + m - 21[/tex]

[tex]=> m(m - 21) + 1(m - 21)[/tex]

[tex]=> (m - 21)(m + 1)[/tex]

Step-by-step explanation:

Answer:

x = 6.22 cm

Step-by-step explanation:

The lines on the sides of the triangle means they are the same length

Since it is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

Substituting what we know

a^2 + a^2 = x^2

a=4.4

(4.4)^2 + (4.4) ^2= x^2

19.36 + 19.36 = x^2

38.72 = x^2

Taking the square root of each side

6.222539674 = x

Rounding to 3 significant figures

x = 6.22 cm

Answer:

21

Step-by-step explanation:

Remember that the centroid splits the 3 medians of a triangle into a ratio of 1:2

Since TS < TN, TS = 42/2 = 21

Complete question:

what is the answer to 22 +10x = 0

Answer:

the value of x is -2.2

Step-by-step explanation:

Given;

22 +10x = 0

collect like terms

10x = 0 - 22

10x = -22

divide both sides by 10

[tex]\frac{10x}{10} = \frac{-22}{10} \\\\x = -2.2[/tex]

Therefore, the value of x is -2.2

Answer:

a) 2x + 1, 4x + 7

b) L = 19 cm, W = 7 cm, A = 133 cm^2

Step-by-step explanation:

8x^2 + 18x + 7

ax^2 + bx + c

ac = 8 * 7 = 56

56 = 4 * 14

8x^2 + 18x + 7 =

= 8x^2 + 14x + 4x + 7

= 2x(4x + 7) + 1(4x + 7)

= (2x + 1)(4x + 7)

a) 2x + 1, 4x + 7

b)

2(3) + 1 = 7

4(3) + 7 = 19

A = LW = 19(7) = 133

Given that,

An egg takes 198 seconds to boil a perfect egg has an altitude of -418 m.

Also it takes 209 seconds at an altitude of 8848 m.

To find,

The domain of T.

Solution,

Domain is the set of input values for which the function is defined. The least value is -418 m and the highest value is 8848 m. So, the domain is :

[tex]-418\le x \le 8848[/tex]

Therefore, this is the required solution.

Answer:

Answer:

67.5

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the enlargement or reduction of an object by a factor.

The area of ABCD = AB * BC = 30

As a result of the dilation to form A'B'C'D', A'B' = 3/2 * AB, B'C' = 3/2 * BC, C'D' = 3/2 * CD and A'D' = 3/2 * AD. Hence:

Area of A'B'C'D' = A'B' * B'C' =  3/2 * AB * 3/2 * BC = 9/4 * (AB * BC) = 9/4 * 30 = 67.5

Answer:

the transformation quadrilateral ABCD undergoes is a reflection.

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get the equation

y ∝ x

y = kx

k = y/x

here k is the constant of variation.

From the table,

substitute x = -3, y = -4 in the equation

k = y/x

k = -4/-3

k = 4/3

substituting x = -2, y = -1

k = y/x

k = -1/-2 = 1/2

substituting x = -1, y = 2

k = y/x

k = 2/-1 = -2

substituting x = 0, y = 5

k = y/x

k = 5/0 = ∞

substituting x = 1, y = 8

k = y/x

k = 8/1

k = 8

substituting x = 2, y = 11

k = y/x

k = 11/2

substituting x = 3, y = 14

k = y/x

k = 14/3

It is clearly visible that there is no constant of variation because the ratio y = k/x is variating for different ordered pairs.

Thus, It is clear that none of the answers in the answer choices represent the constant of variation in this relation.

Answer:

Let the two angles be x and 2x

Sum of angles of triangle=180°

Step-by-step explanation:

Answer: 12x+8y=80

8x-2y=60

Step-by-step explanation:

The equations that could be part of the process of solving this system are 12x+8y=80 and 8x-2y=60.

The original equation was 3x+2y= 20 and 4x-y=30. Multiplying all through by 4 gives 12x+8y=80 and 8x-2y=60.
