this is the last question i got a 100 so far can we get a full 100

Answer:

20

Step-by-step explanation:

Given the expression

x(x + 3) + 2 for x = 3

Substitute x =3 into the equation

f(3)= 3(3+3)+2

f(3) = 3(6)+2

f(3) = 18+2

f(3) =20

Hence the value of the expression when x = 2 is 20

Answer:

Yes. A double negative is the same thing as a single positive.

Answer:

Step-by-step explanation:

     4x+8                  27

L-------------M-------------------------N

<------------------ 6x -------------------->

LM = 4x+8

MN = 27

LN = 6x

LM + MN = LN

4x+8 + 27 = 6x

35 = 2x

17.5 = x

LN = 6x = 6(17.5) = 105

The correct answer to the question is: x = 17.5, LN = 105

From the question given above, we obtained the following:

LN = 6x

LM = 4x + 8

MN = 27

The value of x can be obtained as follow:

LN =  LM + MN

6x = 4x + 8 + 27

6x = 4x + 35

Collect like terms

6x – 4x = 35

2x = 35

Divide both side by 2

x = 35 / 2

x = 17.5

LN =?

LN = 6x

LN = 6(17.5)

Therefore, the correct answer to the question is: x = 17.5, LN = 105

Answer:

Solving the similar triangles, we get x=10.6, y=66

Step-by-step explanation:

The triangles are similar.

We need to find the values of x and y

If the triangles are similar, the ratio of corresponding sides is equal.

So, we can write:

[tex]\frac{32}{x}=\frac{30}{10}=\frac{y}{22}[/tex]

Now, we can solve to find value of x and y

First solving to find value of x:

[tex]\frac{32}{x}=\frac{30}{10}\\Cross \:multiply\\32\times 10=30x\\320=30x\\x=\frac{320}{30}\\x=10.6[/tex]

So, we get x = 10.6

Now, finding value of y:

[tex]\frac{30}{10}=\frac{y}{22}\\Cross\:Multiply:\\30*22=10y\\660=10y\\y=\frac{660}{10}\\y=66[/tex]

So, we get y = 66

Solving the similar triangles, we get x=10.6, y=66

Answer:

h = -12/23

Step-by-step explanation:

Combine like terms:

32h + 24 = -3h - 11h

32h + 24 = -14h

Subtract 24 from both sides of the equation:

32h + 24 = -14h

32h + 24 - 24 = -14 h - 24

Simplify:

32h = -14h - 24

Add 14 to both sides and then you simplify. This will give you the answer -12/23. Good luck!!

Answer:

Step-by-step explanation:

1. 40/100 × 129.50 = 51.80

2. 129.50 - 51.80 = 77.70

3. 15/100 × 77.70 = 11.66

4. 77.70 + 11.66 = 66.04

The final cost of the roller blades is $ 89.66

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of purchase be = A

Now , the initial cost of roller blades = $ 129.50

The discount percentage of roller blades = 40 %

So , the equation will be

The cost of the roller blades after discount = 129.50 - ( 40/100 ) x 129.50

                                                                        = 129.50 - 51.8

                                                                        = $ 77.7

Now ,

The sales tax percentage of roller blades = 15 %

So , the equation will be

The cost of roller blades after sales tax = 77.7 + ( 15/100 ) x 77.7

                                                                  = 77.7 + 11.655

                                                                  = $ 89.655

Therefore , the final cost is A = $ 89.66

Hence , The final cost of the roller blades is $ 89.66

Answer:

3/8

Step-by-step explanation:

Given that

Number of clown fish = 10

Number of Angel fish = 4

Number of Puffer fish = 6

Number of Eels = 5

From the above, there exists 10 + 4 + 6 + 5 number of fishes

There exists 25 number of fishes.

Probability of picking a clown fish then is

C = 10 / 25

If the clown fish picked isn't replaced, then there exists 9 clown fishes, and 24 total fishes. This, the probability of picking another clown fish is

C = 9 / 24

C = 3 / 8

Thus, the answer is 3/8

Answer:

a = 49°

Step-by-step explanation:

From the figure attached,

In ΔBOC,

OB = OC = Radii of the circle O

Therefore, m∠OBC = m∠OCB = 41° [Opposite angles of the equal sides of a triangle]

By triangle sum theorem,

m∠OBC + m∠OCB + m∠BOC = 180°

41° + 41° + m∠BOC = 180°

m∠BOC = 180° - 82°

              = 98°

Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference",

m∠BOC = 2(m∠BAC)

98° = 2(a)

a = 49°
