Distribute ^4 to both 2 and q^5

2^4 = 2 x 2 x 2 x 2 = 16
(q^5)^4 = q^20

16(q^20) = 16q^20

16q^20 is your answer

Does anyone know how to do this <br><br>csc x ( sin x + cos x) = 1 + cot x

Dima020 [189]

Explanation:

Use the identities ...

csc(x) = 1/sin(x)

cot(x) = cos(x)/sin(x)

$\csc(x)(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{1}{\sin(x)}(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{\sin(x)}{\sin(x)}+\dfrac{\cos(x)}{\sin(x)}=1+\cot(x)\\\\1+\cot(x)=1+\cot(x)$

The length of a rectangle is 4 less than twice the width. The area of the rectangle is 70

Iteru [2.4K]

w = -5 ; w = 7

Area = Length * Width
Length = 2w - 4
Width = w

70 = (2w - 4)w
70 = 2w² - 4w
2w² - 4w - 70 = 0
2(w² - 2w - 35) = 0
2(w + 5) (w - 7) = 0
w + 5 = 0 ; w -7 = 0
w = -5 ; w = 7

<span>w = -5 is not viable because no length of measurement is negative. </span>
