Learning Task 4. Solve the problem by applying the sum and product of roots
Delvig [45]

Answer:

<em>Thus, the dimensions of the metal plate are 10 dm and 8 dm.</em>

Step-by-step explanation:

For a quadratic equation:

x^2+bx+c=0

The sum of the roots is -b and the product is c. Note the leading coefficient is 1.

We know the perimeter of the rectangular metal plate is 36 dm and its area is 80 dm^2. Being L and W its dimensions, then:

P=2(L+W)=36

A=L.W=80

Note both formulas are closely related to the roots of the quadratic equation, we only need to adjust the data for the perimeter to be exactly the sum of L+W and not double of it.

Thus we use the semi perimeter instead as P/2=L+W=18

The quadratic equation is, then:

x^2-18x+80=0

Factoring by finding two numbers that add up to 18 and have a product of 80:

(x-10)(x-8)=0

The solutions to the equation are:

x=10, x=8

Thus, the dimensions of the metal plate are 10 dm and 8 dm.

Find the present balance.
Triss [41]
<h3>Credited balance:-</h3>

\\ \rm\longmapsto 115.90+115.90+345.85

\\ \rm\longmapsto 231.80+345.85

\\ \rm\longmapsto 577.65

<h3>Debited amount:-</h3>

\\ \rm\longmapsto 25.85+2.00

\\ \rm\longmapsto 27.85

<h3>Checked amount:-</h3>

\\ \rm\longmapsto 19.45+21.02+95.98

\\ \rm\longmapsto 117+19.45

\\ \rm\longmapsto 136.45

<h3>Total change in balance</h3>

\\ \rm\longmapsto 577.65-(27.85+136.45)

\\ \rm\longmapsto 577.65-191.3

\\ \rm\longmapsto 386.35

Now

<h3>Current balance</h3>

\\ \rm\longmapsto 386.35+271.31

\\ \rm\longmapsto\$ 657.66
