Answer:

x =320

Step-by-step explanation:

Given

x^2 + 200x = 166400

Required

Find x

We have:

x^2 + 200x = 166400

Rewrite as:

x^2 + 200x - 166400 = 0

Expand

x^2 + 520x - 320x - 166400 = 0

Factorize

x(x + 520) - 320(x + 520)= 0

Factor out x + 520

(x - 320) (x + 520)= 0

Split

x - 320 = 0\ or\ x + 520= 0

Solve

x = 320\ or\ x =- 520

Side length must be positive;

So:

x = 320

Which equation shows y=3/4x−52 in standard form? 4x−3y=10 4x−3y=−10 3x−4y=10 3x−4y=−10
snow_tiger [21]

Y = 3/4x - 5/2....subtract 3/4x from both sides
-3/4x + y = -5/2 ....multiply everything by common denominator of 4
-3x + 4y = -10

Lizzy wants to solve the equation 6(2x + 1) = 4x – 5. Which step would be an appropriate first step for Lizzy to take to solve f
e-lub [12.9K]

Answer:

distribute parenthesis

Step-by-step explanation:

6(2x + 1) = 4x - 5 ← distribute parenthesis on left side

12x + 6 = 4x - 5 ( subtract 4x from both sides )

8x + 6 = - 5 ( subtract 6 from both sides )

8x = - 11 ( divide both sides by 8 )

x = - \frac{11}{8}
