Solve using quadratic formula 2x^2-64x+494=0

x = 19 or x = 13

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 - 64 x + 494 = 0

Divide both sides by 2:

x^2 - 32 x + 247 = 0

Subtract 247 from both sides:

x^2 - 32 x = -247

Add 256 to both sides:

x^2 - 32 x + 256 = 9

Write the left hand side as a square:

(x - 16)^2 = 9

Take the square root of both sides:

x - 16 = 3 or x - 16 = -3

Add 16 to both sides:

x = 19 or x - 16 = -3

Add 16 to both sides:

x = 19 or x = 13

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
