Answer:

B -1/5

you have to follow pemdas first get rid of the parethase which leaves you with 2+3x+6x=-4x+8x+1 then you add what you can do then you get 2+9x=4x+1 then you subtract 2 from both sides and subtract 4x from both sides which leaves you with 5x=-1 then you divide 5 from both sides and get x=-1/5

Solve the equation by factoring.
Delicious77 [7]

Factorizing an expression involves writing the expression in simpler forms

The values of z are z = \frac 15 or z=4

The equation is given as:

5z^2 - 21z + 4 = 0

Expand the equation

5z^2 - 20z -z + 4 = 0

Factorize the expression:

5z(z - 4) -1(z - 4) = 0

Factor out z - 4

(5z - 1)(z - 4) = 0

Split

5z -1 = 0 or z - 4 = 0

Solve for z

z = \frac 15 or z=4

Hence, the values of z are z = \frac 15 or z=4

Can u guys please help me!!
Alona [7]

Answer and Step-by-step explanation:

This problem requires the use of trigonometric functions, specifically the tangent trig function.

tan(Angle)=\frac{opposite}{adjacent}

Plug in the values.

tan(40) = \frac{8000}{x}

Multiply by x to both sides, then divide by tan(40) to both sides.

x = \frac{8000}{tan(40)}

Now, plug this into a calculator and rounded to the nearest whole number (foot).

x = 9534.0287

x = 9534 ft.

The answer is 9534 ft., the last option.
