Answer:

x = 360/7

Step-by-step explanation:

the sum of 3x and 2/4x is supposed to be 180 degrees.

1.- write it as an equation.

3x + 1/2x = 180

2.- Combine like terms.

3x + 1/2x = 7/2x

7/2x = 180

3.- divide.

180 / 7/2 = 360/7

Answer:

[tex] \boxed{(x + 6)(x - 3)} [/tex]

Step-by-step explanation:

[tex] = > {x}^{2} + 3x - 18 \\ \\ = > {x }^{2} + (6 - 3)x - 18 \\ \\ = > {x }^{2} + 6 x - 3x - 18 \\ \\ = > x(x + 6) - 3(x + 6) \\ \\ = > (x + 6)(x - 3)[/tex]

Answer: (5, 12, 13).

Step-by-step explanation:

Pythagorean triples are any three side lengths of a right triangle that are all whole numbers.

The most common triples are (3, 4, 5), (5, 12, 13), and (9, 40, 41).

You can test the options given in the Pythagorean theorem to see if they make the theorem correct.

25 + 64 = 100 is not correct.

9 + 16 = 36 is not correct.

25 + 144 = 169 is correct.

1 + 1 = 4 is not correct.

The correct choice is (5, 12, 13).

Answer:

Third answer is correct

Step-by-step explanation:

PYTHAGORAS theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Let's take one by one.

1)(5,8,10)

[tex] {5}^{2} + {8}^{2} = {10}^{2} \\ 25 + 64 = 100 \\ 89 = 100[/tex]

No,it's not correct.

2)(3,4,6)

[tex] {3}^{2} + {4}^{2} = {6}^{2} \\ 9 + 16 = 36 \\ 25 = 36 [/tex]

No, it's not correct.

3)(5,12,13)

[tex] {5}^{2} + {12}^{2} = {13}^{2} \\ 25 + 144 = 169 \\ 169 = 169[/tex]

Yes,it's correct

4)(1,1,2)

[tex] {1}^{2} + {1}^{2} = {2}^{2} \\ 1 + 1 = 4 \\ 2 = 4 [/tex]

No, it's not correct

SO, IT'S CLEAR THAT THE CORRECT ANSWER IS THE THIRD ANSWER

Answer:

The zeros are {2, 3}

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:  

F(x) = x^3 - 5x^2 - 6x

Factoring out x, we get:

F(x) = x(x^2 - 5x - 6)

Factoing the quadratic, we get:

F(x) = x(x - 3)(x - 2) = 0

The zeros are {2, 3}

Answer:

x = 3, y = 6

Step-by-step explanation:

In the figure attached,

If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.

By this property,

[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]

[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]

[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]

[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]

3x = 2x + 3

3x - 2x = 3

x = 3

Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]

[tex]\frac{3}{2}=\frac{y}{4}[/tex]

y = [tex]\frac{3\times 4}{2}[/tex]

y = 6

Answer:

C

Step-by-step explanation:

Answer:

He runs 2/3 mile in 8 mins, he runs one mile in 12 mins

It will take Joseph 12minutes to run 1 mile

Speed is defined as the ratio of the distance covered to the time taken.

If Joseph runs 2/3 of a mile in 8 minutes, then;

[tex]\frac{2}{3} miles = 8minutes[/tex]

In order to calculate the time it will take Joseph to run 1 mile, we can write:

[tex]1mile=x[/tex]

Divide both expressions

[tex]\dfrac{\frac{2}{3} }{1} =\dfrac{8}{x} \\\dfrac{2}{3}=\dfrac{8}{x}[/tex]

Cross multiply

[tex]2x=3 \times 8\\2x=24\\x=\frac{24}{2} \\x=12minutes[/tex]

This shows that it will take Joseph 12minutes to run 1 mile.

Answer:

C

Step-by-step explanation:

just divide 1 by 16

Answer:

C

Step-by-step explanation:

The slope is 1.  Note how each time x increases by 1 unit, y also increases by 1 unit.

The y-intercept is (0, -1).

Answer C is correct.

The conversion rate of millimetres to centimetres is 10 = 1 (Meaning 10 millimetres will equal one centimetre).

Knowing this, we can convert the centimetres to millimetres by multiplying by 10.

30 x 10 = 300

So a walking stick is 300 millimetres long.

To find the difference, we need to subtract the larger number from the smaller one.

300 - 10 = 290

Therefore the answer is 290mm.

Answer: -770, -410, 310, 670 degrees

Step-by-step explanation:

Coterminal angles are angles that are have the same sides ... they are essentially the same angle, but are, for example, rotated an extra 360 degrees.

You can add/subtract 360 degrees to check if angles are coterminal:

-770 = -50 - 360 - 360    -- YES, it is coterminal with a -50 degree angle.

-530 [tex]\neq[/tex] -50 - 360 ...      -- NO

-410 = -50 - 360       -- YES

50 [tex]\neq[/tex] -50 + 360 ...      -- NO

310 = -50 + 360     -- YES

360 [tex]\neq[/tex] -50 + 360 ...      -- NO

410 [tex]\neq[/tex] -50 + 360 ...      -- NO

670 = -50 + 360 + 360     -- YES

Answer:

The expression is; x^2 – 4c + 4

Step-by-step explanation:

For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;

This creates of following expression;

x^2 - 4x + c

In order to be a perfect square, the discriminant needs to be zero ;

( - 4 )^2 - 4 * ( 1 )c = 0 ,

16 – 4c = 0 ,

4c = 16 ,

c = 4 ,

Solution; The expression is, therefore; x^2 – 4c + 4
