The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width

Answers

Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

A=320^2!
Length x width = area

Find the discriminant and the number of real roots for this equation.

4x2 + 12x + 9 = 0

A. -144; one real root

B. -144; no real roots

C. 0; one real root

D. 0; two real roots

Answers

Discriminant and the number of real roots for this equation are 0, one real root.

What is discriminant?

Discriminant of a polynomial in math is a function of the coefficients of the polynomial.

The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

Given equation

[tex]4x^{2} +12x+9 = 0[/tex]

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]

= [tex]\sqrt{144-144}[/tex]

D = 0

Therefore, number of real roots is one.

Hence, discriminant and the number of real roots for this equation are 0, one real root.
