Using the PEMDAS method will allow you to solve the expression. First, (-10)-(-11)= 1. Then you would subtract the -10 which would give you -9 as your full answer!

<h3>Answer:<u>3 /6  ÷  9 /18  is  1 /1 </u></h3>

Step-by-step explanation: Steps for dividing fractions

Find the reciprocal of the divisor

<u>Reciprocal of  9/ 18 : 18 /9  Now, multiply it with the dividend So,  3/ 6  ÷  9/18  =  3 /6  ×  18 /9 =  3 × 18/ 6 × 9  =  54/ 54 </u>

<u>After reducing the fraction, the answer is  </u>

Trapezoid GHJK was rotated 180° about the origin to determine the location of G'H'J'K', as shown on the graph. What are the coor
ahrayia [7]

Answer:

when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k). The signs of the coordinates change .

In the given graph point H' is (-3,-2) .The pre image of this point will be point H .Point H will have coordinates which will have signs of both coordinates opposite to that  of point H'.

Coordinates of point H will be (3,2)

Factor the polynomial completely.
Mrrafil [7]

Answer:

The factors of the polynomial: (b⁴ - 2)(b² - 3)

Step-by-step explanation:

The given polynomial is: $ \textbf{b}^{\textbf{6}} \textbf{-3b}^{\textbf{4}} \textbf{-2b}^{\textbf{2}} \textbf{+ 6} $

We can factor the given polynomial by grouping.

We get: $ \{ b^6 - 3b^4\} + \{2b^2 + 6\} $

$ = b^4 (b^2 - 3) -2(b^2 - 3) $

Taking (b² - 3) common outside, we get:

$ = \{b^2 - 3\} \{b^4 - 2\} $

Hence the polynomial $ b^6 - 3b^4 - b^2 + 6 $ can be factored as $ (b^4 - 2)(b^2 - 3) $.

Hence, the answer.

The longest side of a right triangle is 15 feet. The third side is 15 less than three times the shortest side. Find the length o
luda_lava [24]

Answer: The shortest side is 9ft

Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).

If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).

Now we have three sides of a triangle which we can label as 15, x and 3x - 15

By applying the Pythagoras theorem, AC² = AB² + BC²

(Where AC is the hypotenuse and AB and BC are the other two sides)

15² = X² + (3x-15)²

By expansion, (3x-15)² becomes 9x² - 90x + 225

Hence, 225 = X² + 9X² - 90X + 225

225 = 10X² - 90X + 225

Subtract 225 from both sides of the equation

10X² - 90X = 0

Factorize the left hand side of the equation by 10x

10x (x - 9)= 0

Therefore, either

10x = 0 OR

x - 9 = 0

If 10x=0, then x=0. OR

If x - 9 = 0, then x = 9

The length of the shortest side is 9ft.
