Answer:

x = 2, -2, -1/5

Step-by-step explanation:

g(x)= 5x^3+x^2-20x-4

g(x)= x^2(5x+1)-4(5x+1)

g(x)=(x^2-4)(5x+1)

g(x)=(x-2)(x+2)(5x+1)

x-2=0

x= 2

x+2=0

x= -2

5x+1=0

x= -1/5

Oksi-84 [34.3K]

Answer:

A = 58.7 degrees

B = 66.9 degrees

C = 34.1 degrees

Step-by-step explanation:

For <A:

Tan A = $\frac{opposite}{adjacent}$

Tan A = $\frac{23}{14}$

Tan A = 1.6

A = $Tan^{-1} 1.6$

A = 58.7 degrees

For <B:

Sin B = $\frac{opposite}{hypotenuse}$

Sin B = $\frac{23}{25}$

Sin B = 0.92

B = $Sin^{-1} 0.92$

B = 66.9 degrees

For <C:

Sin C = $\frac{opposite}{hypotenuse}$

Sin C = $\frac{14}{25}$

Sin C = 0.56

C = $Sin^{-1}0.56$

C = 34.1 degrees

The length of a garden is four more than twice its width, w. Which expressions represent the area of the garden? Select all that

fgiga [73]

Answer: the options that apply are

1) w(2w + 4)

5) 2w² + 4w

Step-by-step explanation:

The formula for determining the area of a rectangular garden ins expressed as

Area = length × width

The length of a garden is four more than twice its width, w. The expression for the length would be

Length = 2w + 4

Therefore, the expression that represents the area of the garden would be

w(2w + 4)

Expanding the brackets, it becomes

2w² + 4w

erica [24]

Answer:

Step-by-step explanation:

$\frac{WX}{p}=q$

Multiply the equation by p

$\frac{WX}{p}*p=q*p\\\\WX = pq\\\\\frac{WX}{W}=\frac{pq}{W}\\\\X =\frac{pq}{W}$
