4 height of a trapezoid is 4 inches the sum of its parallel sides is 14 it’s area is?

Area = 28 sq inches

Step-by-step explanation:

For the area of a trapezoid, you average the parallel sides (add them and divide by 2). Then times by the height.

Its like youre trying to smash it into being a rectangle.

Well, in the question they told you the parallel sides added together is 14. Then divide by 2, which gives you 7. Then times by height: 7×4

=28

Recap:

Area(trapezoid)

= [(base1 + base2)/2]×height

= [(14)/2] × 4

= 7 × 4

= 28

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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
