The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:

6/9=9/15

If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.

To calculate this, we use cross multiplication.

6/9=9/15

6*15=9*9
90=81

90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.

I hope this helps! Please comment if you have any questions.

If 2x + y = 12 and x + 2y = -6, then find the value of 2x + 2y
Sedaia [141]
2x + y = 12
2x = 12 - y

x + 2y = -6
2y = -6 - x

2x + 2y
12 - y + (-6) - x
12 + (- 6) - y - x
12 - 6 - y - x
6 - y - x

Answer: - x - y + 6

6n +3=2 Use a table
taurus [48]
I think that the answer is -1/6. I got this by subtracting 3 on both sides according to the order of operations and got -1. Next, I divided 6 on both sides to undo the multiplication. Since you can't do 1 divided by 6, you can leave it as a fraction which is -1/6.

Which expression has a value of 3?
Marina86 [1]

Step-by-step explanation:

3(4 *to the power of 2* - 3*to the power of 2*)

  • 3(4²-3²)
  • 3(16-9)
  • 3(7)
  • 21

24-23 x 3

  • 24-23×3
  • 24-69
  • -45

3*to the power of 3* - 3*to the power of 2

  • 3³-3²
  • 9-6
  • 3

(6*to the power of 2* - 3) (9*to the power of 2* - 70)

  • (6²-3)(9²-70)
  • (36-3)(81-70)
  • (33)(11)
  • 363

Hence, Option d. is the correct answer because it gives answer 3 when it is solved.
