Answer:

3x³ + 23x² + 63x + 55

Step-by-step explanation:

Given

(3x + 5)(x² + 6x + 11)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis

= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms

= 3x³ + 23x² + 63x + 55

mina [271]
I = p * r * t
264 = p * .06 * 2
264 = .12p
Divide both sides by .12

If the length of the hypotenuse of a right triangle is 39 millimeters and the length of one leg is 15 millimeters what is the le
Genrish500 [490]

Answer:

36 millimeters

Step-by-step explanation:

From Pythagoras theorem, the square of the hypotenuse is equal to the sum of the square of the two other legs

In mathematical terms;

a^2 = b^2 + c^2

Let a represent the hypotenuse = 39 mm and the length of one leg, say c, is 15 mm

Slotting in the values of a and b

39^2 = b^2 + 15^2

1521 = b^2 + 225

collect like terms

1521 - 225 = b^2

1296 = b^2

Take the square root of both sides

36 = b

Therefore b = 36 mm

Sec s = 1.6948
Anastaziya [24]
That'd be true only if the value of "s" is the exact same one for both
namely  if sec(s) = cos(s)
then solving for "s"
thus

\bf sec(s)=cos(s)\qquad but\implies sec(\theta)=\cfrac{1}{cos(\theta)}&#10;\\\\\\&#10;thus\cfrac{1}{cos(s)}=cos(s)\implies 1=cos^2(s)\implies \pm \sqrt{1}=cos(s)&#10;\\\\\\&#10;\pm 1=cos(s)\impliedby \textit{now taking }cos^{-1}\textit{ to both sides}&#10;\\\\\\&#10;cos^{-1}(\pm 1)=cos^{-1}[cos(s)]\implies cos^{-1}(\pm 1)=\measuredangle s
