What's the question
Step-by-step explanation:
You didn't give an actual question, just background information.
A solution of a quadratic equation (ax^2+bx+c) is the point at which the parabola crosses the x-axis. We can find this by using the Quadratic formula, which is
. We can solve the equation as follows:
Then we separate the negative from -28 to get:
Then we continue to solve by factoring common terms (-2 and 2). We get the solutions of
. Choice
B matches our first solution.

1 & 5/8 because 7/8 is closer to 1 whole than 5/8
Answer:
Area = 95.4 cm²
Step-by-step explanation:
Given
θ = 135°
r = 9cm
Required
Calculate the area of the sector
Area of a sector is:
Area = θ/360 * πr²
Substitute values for θ and r
Area = 135/360 * π * 9²
Area = 0.375 * π * 81
Take π as 3.14
Area = 0.375 * 3.14 * 81
Are = 95.3775
Area = 95.4cm² ---- approximated
