Answer:

C) -582°

Step-by-step explanation:

Coterminal angles sum to 360°n, where n is an integer.

Given angle is 138°

The difference is:

A) 438° - 138° = 300°, no
B) -136° - 138° = -274°, no
C) -582° - 138° = -720° = -2(360°), yes
D) 228° - 138° = 90°, no

faltersainse [42]

Set it up as an equation: 12 + 6x = 47
(x is the reduced fee)

12 + 6x = 47
12 - 12 + 6x = 47 - 12
6x = 35
x = 35/6

HELP...The volume of a rectangular prism is 36x^6y^8. The length of the prism is 4x^3y^5, and the width of the prism is 3xy^2. W

Margaret [11]

Answer:

$H = 3x^2y$

Step-by-step explanation:

Given

$V = 36x&^6y^8$

$L = 4x^3y^5$

$W = 3xy^2$

Required

Find the height of the prism

Volume (V) is calculated as:

$V =LWH$

Substitute values for V, L and W

$36x^6y^8 =4x^3y^5 * 3xy^2 * H$

Make H the subject

$H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}$

$H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}$

$H = \frac{36x^6y^8}{12x^4*y^7}$

Divide:

$H = 3x^{6-4}y^{8-7}$

$H = 3x^2y$

The height of the prism is: $3x^2y$

Write an equation: The sides of a rectangle are x and ( x - 4 ). The perimeter is 87

Svetlanka [38]

The perimeter of a rectangle, is all of the sides added up.

In a rectangle, there are two widths (right and left), and two lengths (up and down)

So:

Perimeter = 2 × width + 2 × length.

To get the equation we just substitute in the values that we are given:

length = (x)

width = (x - 4)

perimeter = 87

So just put these values into: perimeter = 2 × width + 2 × length:

87 = 2(x) + 2(x - 4)

_____________________________

Answer:

The equation is: 87 = 2(x) + 2(x - 4)

(note: this can be simplified down like so:

87 = 2x + 2x - 8

87 = 4x - 8

95 = 4x

23.75 = x
