Check the picture below.

so our bases are "d" and "d+a+b", and a height of "c".

$\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(x+y)}{2}~~ \begin{cases} x,y=\stackrel{parallel~sides}{bases}\\ h~~~=height\\ \cline{1-1} x=d\\ y=d+a+b\\ h=c\\ A=(d+b)c \end{cases}\implies (d+b)c=\cfrac{c[d+(d+a+b)]}{2} \\\\\\ 2(d+b)c=c[d+(d+a+b)]\implies 2dc+2bc=c(2d+a+b)$

$\bf ~~\begin{matrix} 2dc \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~+2bc=~~\begin{matrix} 2dc \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~+ac+bc\implies 2bc=ac+bc\implies 2bc=c(a+b) \\\\\\ \cfrac{2b~~\begin{matrix} c \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} c \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}=a+b\implies 2b=a+b\implies 2b-b=a\implies \blacktriangleright b=a \blacktriangleleft$

Brianna's teacher asks her which of these three expressions are equivalent to each other.

jekas [21]

Brianna's thinking is incorrect.
Expessions A, and C. are equivalent.
For C, you add 5x and x together (because they have the same variable) to get 6x - 4.
For A, you subtract 9x and 3x (because they have the same variable) to get 6x- 4.

Original price is $125

andrey2020 [161]

$125-$81.25 =$43.75 so that is how much was saved. Now figure what percentage $43.75 is of $125. so $43.75÷$125=.35 and changing to % the discount is 35%

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million u

EleoNora [17]

Answer:

when the survey was initially conducted the average sales of smartphones was 1.7 million units

Step-by-step explanation:

The average annual sales of smartphones is given by function

$P(n)= 1.7 (b)^n$

Exponential growth function is given by

$f(x)= ab^x$

Where a= initial value

b = growth factor , b= 1+r where 'r' is the growth rate

x is the time period

Now we compare f(x) with P(n)

the value of a= 1.7 that is the initial value.

So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
