Answer:

B. 29º

Step-by-step explanation:

Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:

[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)

In addition, the sum of internal angles in triangles equals 180º, which implies that:

[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)

If we know that  [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:

[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]

[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]

[tex]\angle A = 29^{\circ}[/tex]

Hence, correct answer is B.

Answer:

the value of the equation is -1

Answer:

15 inches.

Step-by-step explanation:

V = 1/3 pi r^2 h

7065 = 1/3 * 3.14 * 30 * r^2

r^2  = 7065 / (1/3 * 3.14 * 30)

r^2 = 7065 / 31.4 = 225

r = sqrt 225 = 15.

Answer:

[tex]\boxed{\bold{\left(2x-1\right)\left(4x^2+2x+1\right)}}[/tex]

Explanation:

Apply difference of cubes formula: [tex]\bold{x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)}[/tex]

[tex]\bold{\left(2x\right)^3-1^3=\left(2x-1\right)\left(2^2x^2+2x+1\right)}[/tex]

= [tex]\bold{\left(2x-1\right)\left(2^2x^2+2x+1\right)}[/tex]

2² = 4

[tex]\boxed{\bold{\left(2x-1\right)\left(4x^2+2x+1\right)}}[/tex]

Answer:

(see my explanation)

Step-by-step explanation:

Basically,

For no value it can be anyhting but 8.

For all values it HAS to be 8.

For just one anything that has "x" in it.

Example:

1. -9

2. +8

3. 7+x or 2x

NOTE: this varies depending on the varible after the x value. (It's not always 8)

☝Example:

5x+2 = 5x + _____

1. 3

2. +2

3. x

Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]

x= [tex]\frac{-2}{5}y-2[/tex]

2-  3x+y+−y=66+−y

3x=−y+66

[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]

[tex]x=\frac{-1}{3}y+22[/tex]

Given:

The terms of a sequence are given by

[tex]a_n=-1-4n[/tex]

To find:

The 100th term of the sequence.

Solution:

We have,

[tex]a_n=-1-4n[/tex]

Putting n=100, we get

[tex]a_{100}=-1-4(100)[/tex]

[tex]a_{100}=-1-400[/tex]

[tex]a_{100}=-401[/tex]

Therefore, the 100th term of the given sequence is -401.

Answer:
