The figures are similar. The area of one figure is given. Find the area of the other figure to the nearest whole number.
Akimi4 [234]

Answer:  Option b.

Step-by-step explanation:

First, you need to calculate the ratio of the area. This is:

ratio=(\frac{64}{28})^2\\\\ratio=\frac{256}{49}

You know that the area of the smaller trapezoid is 771 m², then you can set up the following proportion, where "x" is the area of the larger trapezoid. Then you have:

\frac{256}{49}=\frac{x}{771}

Now you must solve for "x". Therefore, you get that the area of the larger trapezoid is:

 x=(771)(\frac{256}{49})\\\\x=4,028m^2

Use the quadratic formula to solve x2 + 2x - 120 = 0. Think about what other method could also be used to solve this equation. a
pshichka [43]

Answer:

x = 10 , -12

Step-by-step explanation:

Solution:-

- The given quadratic equation is to be solved using the quadratic formula. The general form of a quadratic equation is:

                           ax^2 + bx + c =0  

Where, [ a , b and c are constants ]

- The quadratic formula is given as:

                       

                           x = \frac{-b+/-\sqrt{b^2 - 4*a*c} }{2a}

- The given equation is:

                             x^2 + 2x - 120 = 0

Where, a = 1 , b = 2 , c = -120

- Solve using quadratic formula:

                       x = \frac{-2+/-\sqrt{2^2 - 4*1*(-120)} }{2*1}\\\\x = \frac{-2+/-\sqrt{4 + 480} }{2}\\\\x = \frac{-2+/-(22) }{2}\\\\\\x = 10 , -12
