Which expressions are equivalent to 5x square root 28x^5+ 8x^3 square root 7x if x>0?

Answer:

Its actually 6x + 6y because your adding all like variables to simplify the expression and since theirs 6x and 6y the equation becomes 6x + 6y

Answer:

x= -2

Step-by-step explanation:

Move all the terms to the left.

Add all the number together and then add the variables.

Get rid of parenthesis

Move all terms containing x to the left.

The value of x obtained for given diagram is,  12

An angle is a mathematical term which we can defined, when two straight lines or rays meets at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The  inner angle made by the intersection of two polygonal sides.

Exterior angles:-  The  outer angle made by the intersection of two polygonal sides.

Given that,

All the exterior angles are,

(5x + 4), (7x + 4),(4x + 9),(4x + 1),(9x-6)

It is known that,

Sum of Interior angle & Exterior angle is equal to 180°

So we can calculate all the Interior angles,

180°- (5x + 4),  180°-(7x + 4),   180°-(4x + 9),   180°-(4x + 1),    180°-(9x-6)

Formula for sum of all the Interior angles = (2n-4)×90

So, n=5

Sum of all the Interior angles = 540°

[180°- (5x + 4)] + [180°-(7x + 4)]+[180°-(4x + 9)]+[180°-(4x + 1)] +[180°-(9x-6)] = 540

900- 29x- 12 = 540

x = 12

Hence, The value of x is, 12

Answer:

I think its an obtuse triangle

Answer:

- 2/3 is the answer

Answer:

this shape consists of a square and triangle

The shape is a Pentagon ... but that won't help get the perimeter or area. you'll have to find the areas and perimeters of both the square and triangle and then add them for the final answer.

Area of figure = area of square + area of triangle

=> Area of Square = a² (a = side)

side = 3.5 cm ...so...

Area of square = a²

= 3.5 × 3.5

= 12.25 cm²

=> Area of Triangle = ½ × base × height

= ½ × 3.5 × 1.64

= 2.87cm²

Area of figure = area of square + area of triangle

Area of figure = 12.25 + 2.87

= 15.12 cm²

Perimeter of figure = P of square + P of triangle

=> P of square = 4a

= 3.5 × 4

= 14cm

=> P of isosceles triangle = 2a + base

= 2 × 2.4 + 3.5

= 4.8 + 3.5

= 8.3cm

Total perimeter of figure = P of square + P of triangle

Total perimeter = 14 + 8.3

= 22.3 cm

Answer:

29 minutes

Step-by-step explanation:

Given

[tex]Total = \$43.25[/tex]

[tex]Entrance\ Fee = \$7[/tex]

[tex]Per\ Minute = \$1.25[/tex]

Required

Determine the number of minutes (t) that he was on the trampoline.

This can be expressed as:

[tex]Total\ Payment = Entrance\ Fee + Amount\ per\ minute * t[/tex]

Where t represents the number of minutes

Substitute values for Total, Entrance Fee and Amount per minute

[tex]43.25 = 7 + 1.25 * t[/tex]

[tex]43.25 = 7 + 1.25t[/tex]

Solving further to get the value of t, we have:

[tex]1.25t = 43.25 - 7[/tex]

[tex]1.25t = 36.25[/tex]

[tex]t = 36.25/1.25[/tex]

[tex]t = 29[/tex]

Answer:

29 minutes

Step-by-step explanation:

7 + 1.25t = 43.25 is the equation

How did I solve this?

I divided those two and that is how you get the equation

In total is 29 minutes

Answer:

c=√a²b²

Step-by-step explanation:

The positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

It is given that the formula of the Pythagorean theorem for a right-angle triangle is, a² + b² = c².

The value of c is calculated as:-

a² + b² = c²

Reverse the equation to calculate a.

c² =  a² + b²

Taking b² to the left side then the equation will become:-

a² = c² - b²

Taking square root on both sides of the equation.

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

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

Therefore, the positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

Step-by-step explanation:

Given that:

y = 2x

where y is the number of scoops of juice mix, and x is the liters of water required.

To determine the liters of water required for 16 scoops of juice mix;

y = 16

So that,

16 = 2x

x = [tex]\frac{16}{2}[/tex]

  = 8

x = 8 liters

Therefore, Austin would combine 8 liters of water to the 16 scoops of juice mix.

Step-by-step explanation:

Given parameters;

 Coordinates of the line;

            (-2, -3)

  Slope of the line  = 3

Unknown:

Equation of the line = ?

Solution:

The equation of any straight line is often expressed as;

            y  = mx + c

y and x are the coordinates

c is the intercept

  Now insert values of y, x and m to find c;

   -3  = 3(-2) + c

   -3  = -6 + c

    c = -3 + 6  = 3

The equation of the line is;
