if f(x)=3(x+5) +4/x, what is f(a+2)​

Answer:

x = 95

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360

x +115+46+ 104 = 360

Combine like terms

x+265=360

Subtract 265 from each side

x +265-265 = 360-265

x = 95

Answer:

a) 15.5 cm

b) 37.2 cm

Step-by-step explanation:

For part a you would write 4(x+1) because perimeter is adding the sides and all sides of a square are equal. then you would set that equal to 66 and get 4(x+1)=66 and then distribute the 4 and get 4x+4=66 and then subtract the 4 from 66 and get 4x=62. Then you divide 62 by 4 and get 15.5.

For part b you do essentially the same thing but set it equal to 152.8 and get 4(x+1)=152.8 and then distribute the 4 to get 4x+4=152.8 then subtract the 4 and get 148.8 and then divide that by 4 and get 37.2.

Answer:

Step-by-step explanation:

a) Length = (x +1)  cm

Perimeter of square = 66 cm

4 * length = 66

4* (x +1) = 66

Divide both sides by 4

[tex]\frac{4*(x +1)}{4}=\frac{66}{4}[/tex]

x + 1 = 16.5

Subtract 1 from both sides,

x = 16.5 -1

x = 15.5 cm

b) Length = (x +1)  cm

Perimeter of square = 152.8 cm

4 * length = 152.8

4* (x +1) = 152.8

Divide both sides by 4

[tex]\frac{4*(x +1)}{4}=\frac{152.8}{4}[/tex]

x + 1 = 38.2

Subtract 1 from both sides,

x = 38.2 -1

x = 37.2 cm

Answer:

15/19 is a rational number. this is because irrational numbers cannot be represented by fractions

Answer:

The least is 9950 and the largest is 10049 people

Step-by-step explanation:

If the number is rounded to the nearest hundred, the smallest number of people that could have attended the parade is 9950 because, rounding up the number 9950 to the nearest hundred would give 10000. If the number 9950 is decreased by 1 (9949), and rounded up to nearest hundred you won't get 10000. Hence the smallest number of people is 9950

While the largest number of people is 10049. 10049 to the nearest hundred  is 10000. A further increase to the number 10049 would give a number greater than 10000 when rounded to nearest hundred.

Answer:

x = 5

Step-by-step explanation:

2 (4x + 3y = 26)

3 (3x - 2y = 11)              

8x + 6y = 52

9x - 6y = 33                  [the 6y and -6y cancel out]

17x = 85                        [divide both sides by 17 to find x]

x = 5

Step-by-step explanation:

Hey, there!!

Given,

4x + 3y = 26........(i)

3x -2y = 11............(ii)

Multiplying equation (i) by 2 and equation (ii) by 3 we get,

8x - 6y = 52

9x + 6y = 33

17x = 85 { cancelling 6y and -6y}.

[tex]x = \frac{85}{17} [/tex]

Therefore, x= 5.

Now, putting the value of x is equation (i)

4x + 3y = 26

4×5 + 3y = 26

20 + 3y = 26

3y = 26 -20

[tex]y = \frac{6}{3} [/tex]

Therefore, y = 2.

Step-by-step explanation:

In the diagram BC=9. Find ABOUT and AC

The greatest common factor of 18 and 35 is 1.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The greatest common factor of 18 and 35.

Now,

See all the factors of 18.

= 1, 2, 3, 6,  9, and 18.

See all the factors of 35.
= 1, 5, 7, and 35.

We see that,

The greatest common factor is 1.

Thus,

The greatest common factor of 18 and 35 is 1.

[tex]\boxed{235}[/tex]

Step-by-step explanation:

Hey there!

Well given that,

a = 25

b = 3

10(25) - 5(3)

250 - 15

= 235

Hope this helps :)

Hi there! Hopefully this helps!

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

First we need to substitute the value of the variable into the expression:

10a - 5b = 10(25) - 5(3).

Now we Multiply 10 and 25 to get 250.

250 − 5 × 3 = 235

Multiply 5 and 3 to get 15.

250 − 15 = 235

Answer:

-3

Step-by-step explanation:

To find:

The value of '?' in the following expression:

[tex]x^2y^8.x^3y^? = x^5y^5[/tex]

Solution:

First of all, let us have a look at a few rules of the exponents:

[tex]1.\ a^b.a^c=a^{b+c}[/tex]

[tex]2.\ a^b.a^{-c}=a^{b-c}[/tex]

Let us apply these rules and try to find out the missing value ('?') in the given expression.

Left Hand Side (LHS):

[tex]x^2y^8.x^3y^?\\\Rightarrow x^2.x^3.y^8.y^?\\\Rightarrow x^{2+3}y^{8+?}\\\Rightarrow x^{5}y^{8+?}[/tex]

Now, let us compare the LHS with RHS, we get:

[tex]x^{5}y^{8+?} = x^{5}y^{5}[/tex]

Dividing with [tex]x^5[/tex] on both sides:

[tex]y^{8+?} = y^5\\\Rightarrow 8+? = 5\\\Rightarrow ? = 5-8 \\\Rightarrow ? =-3[/tex]

Therefore, the missing value in the expression is -3.

Answer:

-3

Rules of the exponents power:

1.  a^b * a^c = a^(b+c)

2. a^b * a^(-c) = a^(b-c)

Applying these rules on Left Hand Side of the expression given:

= x2y8 * x3y?

= x2x3 * y8y?

= x^(2 + 3) * y^(8 + ?)

Right hand side of the expression given:

= x5y5

Comparing the LHS and RHS, we get

x5y^(8 + ?) = x5y5

Dividing with x5 on both sides:

y^(8 + ?) = y5

8 + ? = 5

? = 5 - 8

? = -3

Therefore, the missing value in the expression is -3.

Answer:

22

Step-by-step explanation:

Given that T is the midpoint of line PQ, PT and TQ are both equal segments of line PQ.

PT is given as 5x + 2,

TQ = 7x - 6

Therefore:

[tex] 5x + 2 = 7x - 6 [/tex]

Solve for x

[tex] 5x + 2 - 7x = 7x - 6 - 7x [/tex]

[tex] -2x + 2 = -6 [/tex]

[tex] -2x + 2 - 2 = -6 - 2 [/tex]

[tex] -2x = -8 [/tex]

[tex] \frac{-2x}{-2} = \frac{-8}{-2} [/tex]

[tex] x = 4 [/tex]

PT = [tex] 5x + 2 [/tex]
