There are fours ways to solve polynomial equations..........
Polynomial Equation Degree Example
Linear Equations 1 -3x + 1 = 4x + 5
Quadratic Equations 2 x2 – 6x + 9 = 0
Cubic Equations 3 x3 – 2x2 + 3x = -5
Quartic Equations 4 x4 – 2x2 = -4
It's really not that hard.....
Answer: 357 cm²
Step-by-step explanation: In this problem, were asked to find the area of the trapezoid shown. Remember that a trapezoid is a quadrilateral with one pair of parallel sides. The formula for the area of a trapezoid is shown below
The b's are the bases or the parallel sides and the h represents the height.
So in the trapezoid shown, the bases are 15 cm and 27 cm and the height is 17 cm.
Plugging this information into the formula, we have .
Next, the order of operations tells us that we must simplify inside the parentheses first. 15 cm + 27 cm is 42 cm and we have
1/2 × 42 cm is 21 cm and we have (21 cm)(17 cm) which is 357 cm².
So the area of the trapezoid shown is 357 cm².
Take the point (10,5)
5 = constant / 10
constant = 5*10 = 50
also for the point (4 , 12.5) constant = 4*12.5 = 50
Answer is 50
