write a polynomial expression that represents the area of a trapezoid with bases of 6x-5 and 4x+7, and a height of x+1.​
tigry1 [53]

Answer:

A = 5x² + 6x + 1

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (a + b)

where h is the height and a, b the parallel bases, thus

A = \frac{1}{2} (x + 1)(6x - 5 + 4x + 7)

   = \frac{1}{2} (10x + 2)(x + 1)

   = (5x + 1)(x + 1) ← distribute using FOIL

   = 5x² + 6x + 1

Taya2010 [7]

There 5 5 dollars in the amount given by the teller to Neka

What is the  total value of a single denomination?

The total value of a single denomination is the number of that denomination received by Neka multiplied by the value of each denomination

In other words, the total value of 50-dollar is $50 multiplied by 2 since there 2 50- dollar bills, the same applies all other bills.

Total amount=($50*2)+($20*6)+($5*f)

total amount=$245

$245=($50*2)+($20*6)+($5*f)

$245=$100+$120+($5*f)

$245=$220+($5*f)

$245-$220=$5*f

$25=$5*f

f=$25/$5

f=5

In essence, there are 5 5 dollar bills
