how many solutions does d+6+2d=4d+9 have?

Answer:

33cm ; 53 cm

Step-by-step explanation:

Let the length of one piece = x cm

Length of the other piece = (x + 20) cm

x + ( x+ 20) = 86 cm

x + x + 20  = 86

     2x + 20 = 86

              2x = 86- 20

             2x = 66

               x = 66/2

                x = 33 cm

Length of the longer piece = x + 20 = 33 +20 = 53 cm

Answer:

20

Step-by-step explanation:

The total degrees in a circle is 360 degrees

x+40+2x+110+3x+90 = 360

==> 6x = 120

x = 20

Answer:

The answer would be x=20

Answer:80,65,20

Step-by-step explanation:

In general, a unique triangle may always be drawn if three side lengths are given and the sum of any two is greater than the third. c) More than one triangle can be drawn with Angle A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

Answer:

x = 60

Step-by-step explanation:

Remark

The two angles that are equal are remote interior angles. They add to 120

Step one

y + y = 120               Combine

2y = 120                  Divide by 2

y  = 120/2

y = 60

Step Two

Find the angle vertically opposite to the 60 degree angle near the center on the left hand triangle.

The vertically opposite angle is 60. If you know one vertically opposite angle, you know the other one.

Step Three

State the value of the angle that is vertically opposite x.

The angles value is 60o. You are working with an isosceles triangle according to the markings on the triangle.

Step Four

State the value of x

The value of x = 60 degrees. It is equal to the angle described in step three.

Answer:

It was wrong bro

Step-by-step explanation:

Answer:

Step-by-step explanation:

Sin(x) = opposite / hypotenuse.

opposite = 28  The opposite is not connected to the angle.

hypotenuse= 35

Sin(x) = 28/35 = 4/5

Cos(x) = adjacent / hypotenuse.

The adjacent side is part of the angle

adjacent = 21

hypotenuse = 35

Cos(x) = 21 / 35 = 3/5

Tan(x) = opposite / adjacent

opposite = 28

adjacent = 21

Tan(x) = 28/21

Tan(x) = 4/3

49x

Step-by-step explanation:

Answer:

Step-by-step explanation:

x + x + 65 °+ 25° = 180° ( being sum of angles of triangle )

2x + 90° = 180°

2x = 90°

x = 45

now

<A = 45°

< B = x + 65° = 45 °+ 65 °= 110°

< C = 25°

Hello, I Am BrotherEye

Answer:

This Transparent inquisition can be solved Below

Use transformations to graph a quadratic function in vertex form. A quadratic function in standard form, f(x) = ax² + bx + c, can be changed into vertex form by completing the square. The vertex form of a quadratic function is f(x) = a(x – 5)2 + k, where the vertex of the function is (h, k).

Step-by-step explanation:

Vertex form to standard form converter

Write the parabola equation in the vertex form: y = a*(x-h)² + k ;

Expand the expression in the bracket: y = a*(x² - 2*h*x + h²) + k ;

Multiply the terms in the parenthesis by a : y = a*x² - 2*a*h*x + a*h² + k ;

Best Of Luck

Answer:

The answer is 65

Step-by-step explanation

You need the slant height to find the lateral area of the cone, so using the equation l = √h²+r², you plug in the height for h, the radius for r, and l is the slant height.

l =√12²+5²

l = √144 + 25

l = √169

l = 13

Now that you have the slant height, simply multiply that by the radius and you'll get the lateral area in terms of pi.

Answer:

It's complement is 94%.

Step-by-step explanation:

Complement of a percentage:

The complement of a percentage is 100% subtracted by this percentage.

In this question:

Percentage of 6% for probability of rain.

So the complement, that is, the probability of not raining, is:

100 - 6 = 94%.

Answer:

9.4 feet to the nearest tenth.

Step-by-step explanation:

This makes a right triangle so we use Pythagoras:

23^2 = 21^2 + d^2   where d is the required distance.

d^2 = 23^2 - 21^2

d^2 = 88

d = √88 = 9.3808

Answer:

Um, maybe 21.5?

Step-by-step explanation:

43/2 = 21.5, so maybe

1 = 21.5
