Bogdan [553]3 years ago
5 0

Answer:

The right answer is the second option, 9,747.

Step-by-step explanation:

EG^2 = DG*FG \\ EG^2 = 5*14 \\ EG = \sqrt{70}

Now let's find DE (Pythagorean theorem).

DE^2 = DG^2+EG^2\\ DE = \sqrt{25+70} \\ DE = \sqrt{95}

\sqrt{95} =9,7467... = 9,747

How do I solve this equation and check the solutions?
bearhunter [10]

Answer:

{-6}

Step-by-step explanation:

Step 1 Raise both sides of the equation to the index of the radical in the case 2

(\sqrt{2x+13} )^{2} =(x+7)^{2}

2x + 13 = (x+7)(x+7)

2x +13 = x^{2}  + 14x + 49\\0=x^{2} +12x+36

Step 2 Factor

(x + 6)(x + 6) = 0

x + 6 = 0

x = - 6

Step 3 Check -6

\sqrt{2(-6)+13} = -6 + 7\\\sqrt{-12+13} = 1\\\sqrt{1} = 1\\1 = 1
