Divide a^24-a^18+a^12 by a^6 what is the quotation?

lana66690 [7]

I think you mean "what is the QUOTIENT?"

$\dfrac{a^{24} - a^{18} + a^{12}}{a^6} =$

$= \dfrac{a^{24}}{a^6} - \dfrac{a^{18}}{a^6} + \dfrac{a^{12}}{a^6}$

$= a^{24 - 6} - a^{18 - 6} + a^{12 - 6}$

$= a^{18} - a^{12} + a^{6}$

A projected image appears as an isosceles trapezoid.

Komok [63]

7x + 4 + 9x = 180
16x = 176
x = 11

9x = 9x11 = 99
7x + 4 = 7(11) + 4 = 77 + 4 = 81

in order to form a rectangular image, each angle needs to be equal 90 degreesn

99 - 9 = 90
81 + 9 = 90

In triangle ABC, a = 9, c = 5, and B = 120°. Find b2.

Answer:

(D) $b^2=151$

Step-by-step explanation:

Given: In triangle ABC, a=9, c=5 and ∠B=120°.

To find: The value of $b^2$ .

solution: It is given that In triangle ABC, a=9, c=5 and ∠B=120°.

Now, using the law of cosines, we get

$b^2=a^2+c^2-2(a)(c)cosB$

Substituting the given values, we get

$b^2=9^2+5^2-2(9)(5)cosB$

$b^2=81+25-90(\frac{-1}{2})$

$b^2=81+25+45$

$b^2=151$

which is the required value of $b^2$ .

Therefore, option D is correct.
