10. Rhombus ABCD has vertices at A(-2, 7), B(8, 7), C(2, -1), and D (-8, -1). Determine the area of ABCD.

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

a thesis statement is a topic it is not a fact or a question

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

b is the right answer
