Angelica used the distributive property to simplify the expression. 14(5+8)
In Step 1, Angelica applied the distributive property. She multiplied 14 by each of the addends inside the parentheses. Which expression demonstrates Angelica multiplying 14 by each addend?
(14⋅5)+(5⋅8)
(14⋅5)+(14⋅8)
5+(14⋅8)
(14⋅5)+8

use formula for the circle a=3.14

step-by-step explanation:

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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
