What is the following sum? mc011-1.jpg

the given equation is ,

squaring both sides, we get

x² + 49 = (x+5)²

→ x² + 49 = x² + 10 x + 25

→ 10 x = 25 - 49 →[ cancelling x² from both sides]

→ 10 x = -24

→ x = -24/10= -12/5

but , x = -12/5 does not satisfy the equation, .

so, option (4) no solution, is correct.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
