All you have to do is multiply the l * w = Area

When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.

So the dimensions of the ceiling are l = 20 ft; w = 9 ft

Can somebody please help me with this pleaseee
Semmy [17]

Answer: -2, 2

Step-by-step explanation:

0 = 5x^2 -20

0 = 5(x^2 -4)

0 = 5(x - 2)(x + 2)

0 = x - 2

2 = x

0 = x + 2

-2 = x

Find a third-degree polynomial equation with rational coefficients that has roots -4 and 6 + i.
dolphi86 [110]

Answer:

x³ - 8x² - 11x + 148

Step-by-step explanation:

Given that x = 6 + i is a root then x = 6 - i is also a root

Complex roots occur as conjugate pairs.

The factors are therefore (x - (6 + i)) and(x - (6 - i))

Given x = - 4 is a root then (x + 4) is a factor

The polynomial is the product of the factors, that is

p(x) = (x + 4)(x - (6 + i))(x - (6 - i))

      = (x + 4)(x - 6 - i)(x - 6 + i)

      = (x + 4)((x - 6)² - i²)

      = (x + 4)(x² - 12x + 36 + 1)

      = (x + 4)(x² - 12x + 37) ← distribute

      = x³ + 4x² - 12x² - 48x + 37x + 148

      = x³ - 8x² - 11x + 148

Alenkinab [10]
Hello,

f(x)= \dfrac{4}{x-9} \\&#10;&#10;g(x)= \dfrac{4}{x+9} \\&#10;&#10;f(g(x))=f( \dfrac{4}{x+9} )\\&#10;&#10;= \dfrac{4}{ \dfrac{4}{x+9}-9} \\&#10;&#10;= \dfrac{4(x+9)}{4-9x-81} \\&#10;&#10;=- \dfrac{4x+36}{77x+9x} &#10;&#10;&#10;
