multiiplication or dividsion
additon or subtraction


(4x)^2=4x times 4x
4x^2=4 times x times x=4(x^2)

(4x)^2=16x^2
4x^2=4(x^2)
values are not equal
(just for fun: 4x^2=(2x)^2)

prisoha [69]
My understanding is that when the power is a negative number, move it to the denominator and change it to positive. 
In this case, the base is y, the power is -3

Suppose that ABCD is isosceles with base BC.
nika2105 [10]

It is an isosceles triangle which means that side BD=BC, The angles will be also equal i.e. Angle B= Angle C

<h3>Now,</h3>

  • Angle B = 4x+19
  • Angle C = 2x+33

4x + 19 = 2x + 33

4x + 19 - 2x = 33

4x - 2x = 33 - 19

2x = 14

x = 7

<h3>Calculating the angles:</h3>

∠b = 4x + 19 \\  = 4 \times 7 + 19 \\  = 47

∠c = 2x + 33 \\  = 2 \times 7 + 33 \\  = 47

Now, We will find ∠D with the help of angle sum property of triangle

∠b + ∠c + ∠d = 180 \\ 47 + 47 + x = 180 \\ 94 + x = 180 \\ x =180 - 94 \\ x = 86

<em>The measure of angles are; 47°,47°,86° respectively</em><em>.</em><em>.</em><em>.</em>

What are two possible measures of the angle below? On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis in qu
Neko [114]

Answer:  B)° -270° and 90°

<u>Step-by-step explanation:</u>

Ray 1 is located on the x-axis in Quadrant 1  →  0°

Ray 2 is located on the y-axis in Quadrant 1  →  90° = -270°

The difference between the two angles is:

  • 90° - 0° = 90°
  • -270° - 0° = -270°
