Answer:

C) x2 + x = 306

Step-by-step explanation:

x2 + x = 306

x2 + x - 306  = 0

x2  + 18x - 17x + 18 * (-17) = 0

x ( x + 18) - 17 (x +18) =0

(x + 18) (x - 17 ) = 0

x = -18 or 17

Find x. Round to the nearest tenth.
lions [1.4K]

Answer:

<u>x = 466.7 feet</u>

Step-by-step explanation:

Finding the top angle of the triangle :

  • They are complementary
  • 90° - 31°
  • 59°

Take the tan value of this angle to find y :

  • tan 59° = 400/y
  • 1.66427948 =400/y
  • y = 400 / 1.66427948
  • y = 240.344248

Using Pythagorean Theorem to find x :

  • y² + 400² = x²
  • x = √(240.344248)² + 160000
  • x = √57765.3575 + 160000
  • x = √217765.357
  • <u>x = 466.7 feet</u> (nearest tenth)

2x + y = 3 2x – y = 4 Using elimination to solve this system results in the equation .
DanielleElmas [232]
You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.

2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3 

now that we know our x value, we can plug it into one of the other equations to get our y value.

2(3) + y = 3
6 + y = 3
y = -3

your answer for this system is x=3, y=-3
