The ratio of the sides of a triangle is 2 6 7 if the perimeter of the triangle is 195 meters​
timama [110]

Answer: 91m

Step-by-step explanation:

We set three sides of the triangle equal to 2x,6x,7x; because there is the ratio 2:6:7, which x is a common factor of these three sides.

P = a + b + c

2x + 6x + 7x = 195

    15x = 195

        x = 13

7x suppose be the longest side of the triangle, we plug in 13 for x, then:

7x = 7(13) = 91 m

Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b
LuckyWell [14K]

Answer:

<em>The standard form like (a+bi) will be:  15+8i</em>

Step-by-step explanation:

Given expression is:   2\sqrt{-16}+\sqrt{225}

First factoring out -16 as (-1×16) , we will get....

2\sqrt{-1}*\sqrt{16}+\sqrt{225}

Now, replacing \sqrt{-1} as  i .......

2i\sqrt{16}+\sqrt{225}

Finally, simplifying the radicals in the above expression, we will get......

2i*4+15\\ \\ =15+8i

Thus, the standard form like (a+bi) will be:  15+8i
