Can somebody help me with this math question, all you have to do is answer the equation, then it's described, and then it draw it out I'll give you 100 points and a Brainliest

Answer:

1

Combine multiplied terms into a single fraction

6−8=12(4+5)

6−8=1(4+5)2

2

Multiply by 1

6−8=1(4+5)2

6−8=4+52

3

Add

8

888

to both sides of the equation

6−8=4+52

6−8+8=4+52+8

11(7 + 4) = _ x 7 + 11 x _

use distributive property:

11(7 + 4) = 7 x 11 + 7 x 11

Answer:

11 * 7 + 11 * 4

Step-by-step explanation:

given 11(7+4)

we need to use distributive property

To do so we multiply 11 by whats inside of the parenthesis

so 11(7+4) is equivalent to 11 * 7 + 11 * 4

It will take 40seconds to both the lights to flash at the same time again.

" Least common multiple is defined as the smallest common multiple of the given set of numbers."

According to the question,

Given ,

Time to flash Light A is  every 8 seconds.

Time to flash Light B is every 20 seconds.

Condition given

Both the lights flash at the same time

Least common multiple (8, 20) = 40seconds

Light A flashes in

8seconds , 16seconds , 24seconds , 32seconds, 40seconds

Light B flashes in

20seconds , 40seconds

Hence, both the light flashes at the same time again is at 40seconds.

Answer:

157.1 m

Step-by-step explanation:

Here, we want to calculate the length of the semi-circle

This simply refers to the circumference of the semi-circle

Mathematically, the circumference is half that of a full circle

The circumference of a full circle is;

C = pi * d

For half circle or semi-circle;

It is ;

C = (pi * d)/2

D = 50 m

The circumference is thus;

C = 50 * 3.142

C = 157.1 m

Answer:

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Step-by-step explanation:

1) Use difference of squares: a² - b² = (a + b) (a - b).

[tex]( {x}^{2} - {3}^{2} )(3x + 2)[/tex]

2) Simplify 3² to 9.

[tex]( {x}^{2} - 9)(3x + 2)[/tex]

3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Therefor, the answer is 3x³ + 2x² + -26x -18.

Answer:

7x minus 11

Step-by-step explanation:

7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)

Answer: (B) 7x minus 11

Answer:

x =90

Step-by-step explanation:

Cot 1/2x-1=0

Add 1 to both sides

Cot 1/2x = 0+1

Cot 1/2x = 1

1/tan1/2x = 1

Tan 1/2x = 1

1/2x = arctan1

1/2x =45

x = 45×2

x = 90

Hence the value of x is 90
