Subtract 11b^2 - 46 + 7 from b^2 + 86 - 9.

(b^2 + 8b - 9) - (11b^2 + 4b -7)

b^2 + 8b - 9 - 11b^2 - 4b + 7

- 10b^2 + 12b -16

Step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
