Answer: the expression becomes 2(x +3) - 6.

Let the number be x. Then according to the question,

Step 1 :- Adding 3

=> x + 3

Step 2 :- Multiply the sum by 2

=> 2×(x + 3)

Step 3 :- Subtract 6

=> 2(x +3) - 6

Thus the expression becomes 2(x +3) - 6.

How many unique triangles can be formed with two side lengths of 10 centimeters and one 40° angle?
r-ruslan [8.4K]

Answer:

  • Two unique triangles possible

Step-by-step explanation:

Given two sides of 10 cm and one 40° angle

<u>If we use these, we'll get isosceles triangle with:</u>

1. Included 40° angle.

<u>Then the other angles will be same and measure:</u>

  • (180° - 40°)/2 = 70°

2. Adjacent 40° angle. Then one of the angles must be 40° angle as opposite of 10 cm sides.

<u>The remaining angle will measure:</u>

  • 180° - 2*40° = 100°

There no more unique triangles possible, so the answer is two.
