Answer:

x = 12°

Step-by-step explanation:

To find the value of x, you have to subtract 65 from 180.

This is because angles on a straight line add upto 180 degrees, and 65 is the supplementary angle of 11x -17.

Hence,

11x - 17 + 65 = 180

11x + 48 = 180

11x = 132

x = 12

Answer: x=23

Step-by-step explanation:

180=(3x+18)+93

x=23

Answer:

x = 23°

Step-by-step explanation:

(180° - 93° - 18°) ÷ 3 = (87° - 18°) ÷ 3

= 69° ÷ 3

= 23°

To find:

solve the given problem

Solution:

[tex]\to \bold{20x^{2} +124x+24}\\\\\to \bold{4(5x^{2} +31x+6)}\\\\\to \bold{4(5x^{2} +31x+6)}\ \ \ \ \ \ \ \ \ \ \ 5\times 6= 30 \ \ and\ \ 30 \times 1= 30\\\\\to \bold{4(5x^{2} +(30+1)x+6)}\\\\\to \bold{4(5x^{2} +30x+1x+6)}\\\\\to \bold{4(5x(x +6)+1(x+6)}\\\\\to \bold{4((x +6) (5x+1)}\\\\[/tex]

Therefore, the final answer is "[tex]\bold{4((x+6)(5x+1))}[/tex]".

Answer:

[tex]8.9444 = \sqrt{80} [/tex]

Step-by-step explanation:

the distance is equal to the magnitude or modulus of the vector between the coordinates,

to find the distance, find the vector then the magnitude,ie

vector=

[tex] \frac{4}{2} - \frac{ - 4}{ - 2 } = \frac{8}{4} [/tex]

distance=

[tex] | \sqrt{{8}^{2} + {4}^{2} } | = | \sqrt{64 + 16 } | \\ | \sqrt{80 } | = \sqrt{80} = 8.944[/tex]

Answer:

The second one (Top right)

Answer:

f(x) = x - 2

Step-by-step explanation:

If you notice, the f(x) or y value is 2 less than the x value for every x value listed. This means that x - 2 = y. Just by rearranging this equation, you are given an equation in the linear form y = mx + b:

y = x - 2

Since the y coordinate is being represented by f(x) in the equation, as it is a function, the answer would be:

f(x) = x - 2

Answer:

First number is 63

Second is 5

Last is 6

Step-by-step explanation:

First mutiply both sides by 9:

9(5/9x + 7 = 2/3)

Then simplify:

5x + 63 = 6

For your layout it is:

63 + 5x = 6

The simplified form of the numerical expression (4√15) / √5 will be 4√3.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The ratio is given below.

⇒ (4√15) / √5

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the PEMDAS formula. To answer the problem properly and accurately, this rule must be followed.

⇒ (4√15) / √5

⇒ [4 × √(3 x 5)] / √5

⇒ (4 × √3 × √5) / √5

⇒ 4 × √3

⇒ 4√3

The simplified form of the numerical expression (4√15) / √5 will be 4√3.
