Answer: 78

Explanation: Whenever we deal with an evaluation problem, make sure to always use parenthses when substituting numbers in for variables.

Notice that we have a set of parenthses in our original problem.

To avoid the confusion of having too many sets

of parenthses, let's change the parenthses to brackets.

So we have 2(3) [(5) + 8].

Simplifying from here, we have (6) [(13].

Multiplying, we get 78.

Answer:

D.

Step-by-step explanation:

6*13=78

Step-by-step explanation:

Just consider the inequalities an equal sign and do the usual way of solving:

8x - 6 > 12 + 2x

8x - 2x > 12 +6

6x > 18

x > 3

*The only rule that you need to remember is that when you multiply or divide a negative number on both sides, then the inequality sign would be reverse.*

Example:

-x + 3 > -2

-x > -2-3

-x > -5

Multiplying both sides by -1:

x < 5

The expression which is equivalent to the difference of the given algebraic fraction is,

[tex]\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}[/tex]

Difference is the mathematical operation in which the one number is subtract from another number.

To find the difference of two fraction numbers, we find the least common factor of denominator and write the all numbers as one fraction.

The given expression in the problem is,

[tex]\dfrac{2x+5}{x^2-3x}-\dfrac{3x+5}{x^3-9x}-\dfrac{x+1}{x^2-9}[/tex]

Factorize the denominator of each term as,

[tex]\dfrac{2x+5}{x(x-3)}-\dfrac{3x+5}{x(x-3)(x+3)}-\dfrac{x+1}{(x-3)(x+3)}[/tex]

Here, the least common factor of the denominators is x(x-3)(x+3), therefore, the expression can be written as,

[tex]\dfrac{(x+3)(2x+5)-(3x+5)-(x)(x+1)}{x(x-3)(x+3)}\\\dfr\dfrac{2x^2+5x+6x+15-3x-5-x^2-x}{x(x-3)(x+3)}\\\dfr\dfrac{x^2+7x+10}{x(x-3)(x+3)}\\\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}[/tex]

Hence, the expression which is equivalent to the difference of the given algebraic fraction is,

[tex]\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}[/tex]

A 120° angle and the side lengths can form more than one unique triangles

Malik's claim about the triangle is true

From the question, we have Malik's claim to be:

A 120° angle and side lengths of 3 cm and 4 cm can form more than one unique triangle

The above claim is true;

This is so because, the 120 degrees angle can be between the side lengths of 3 cm and 4 cm and the angle can be located not between the side lengths

This means that there are at least two unique triangles that can be formed using the given parameters

Hence, Malik's claim about the triangle is true

Thank me later.

Answer:

D

Step-by-step explanation:

4x - 12 - x  ≥ 3

Add 12 to both sides.

4x - x ≥ 15

Subtract x (or 1x) from 4x

4x - x = 3x

3x ≥ 15

Divide both sides by 3.

x ≥ 5

From the statement of Hess law, the  ΔH3 is calculated when others are known from; ΔH3 = ΔH4 -( ΔH1 + ΔH2).

Hess law of constant heat summation states that the total heat evolved or absorbed for a series of reactions is the sum of all the heat absorbed or evolved at all steps in the reaction sequence.

Let the heat for the overall reaction be ΔH4 while ΔH1,  ΔH2  and ΔH3 designate the heat of reaction for reactions 1,2,3. It then follows that, the  ΔH3  is calculated when others are known from; ΔH3 = ΔH4 -( ΔH1 + ΔH2).

Supplementary angles

Step-by-step explanation:

The two angles shown are supplementary. You can see if the 3x+15 were to slide down to the next line, how the 3x+15 and 2x would make up a linear pair. Together they add up to 180°

Not sure if you need it, but to solve for x:

3x+15 + 2x = 180

combine like terms.

5x + 15 = 180

Subtract 15.

5x = 165

divide by 5

x = 33

Then you can find the measures of the angles.

Answer:

Joshua is 11 and Mckay is 10.

Answer:

x = 7

y = 7√3

Step-by-step explanation:

Formulas : -

sin θ = opposite side / hypotenuse

When θ = 60,

Opposite side = y

Hypotenuse = 14

sin 60 = y / 14

√3 / 2 = y / 14

y = √3 x 14 / 2

= √3 x 7

y = 7√3

When θ = 30,

Opposite side = x

Hypotenuse = 14

sin 30 = x / 14

1 / 2 = y / 14

x = 1 x 14 / 2

= 1 x 7

x = 7

Note : -

The value of,

sin 30 = 1 / 2

Answer:

  42°, 48°

Step-by-step explanation:

Complementary angles have a sum of 90 degrees. This lets us write the relation ...

  x + (x +6) = 90 . . . . . where x represents the angle; x+6 is its complement

  2x = 84 . . . . . . . collect terms, subtract 6

  x = 42 . . . . . divide by 2

  x +6 = 48 . . . . find the complementary angle

The two angles are 42° and 48°.

A train is moving at a uniform speed of 80 kilometre per hour.

a) how far will it travel in 15 minutes

b) find the time required to cover a distance of 250 km. { as per direct and inverse propositions}.

a)

Given that the train is moving at a uniform speed of 80 km/h.

Time taken = 15 minutes

First we will convert the time

[tex] \small \sf Time \: taken = 15 min = \dfrac{ \cancel{15}}{ \cancel{60}}hr = \dfrac{1}{4}hr [/tex]

Now we will calculate the distance

We know,

[tex] ✪ \: \small\boxed{ \frak{ {Distance }= {Speed} × Time }}[/tex]

Substituting the values in the given formula

[tex] \small\sf{ Distance = \cancel{ 80} \: \: 20 \: km/ \cancel{ hr} × \dfrac{1}{ \cancel{4}} \cancel{hr} =20km }[/tex]

Distance covered in 15 minutes = 20 km

[tex] \rule {40mm}{2pt}[/tex]

b)

Given that the train is moving at a uniform speed of 80 km/h.

Distance covered = 250 km

Calculating the time

We know,

[tex] ✪ \: \small\boxed{ \frak{ Time = \dfrac{Distance}{Speed}}}[/tex]

Substituting the values in the given formula

[tex] \small\sf{ Time = \dfrac{250 km}{80 km/hr} =3 \: hrs \: 20 \: mins }[/tex]
