Please help with math
kykrilka [37]

Answer:

2nd option, x > 1.10

Step-by-step explanation:

7e^{2x}-5 > 58

Add 5 to both sides,

7e^{2x}-5+5 > 58 +5\\7e^{2x} > 63

Divided both sides by 7,

\frac{7e^{2x}}{7} > \frac{63}{7}

e^{2x} > 9

Apply Exponent Rule,

2x > 2ln(3)

\frac{2x}{2} > \frac{2ln(3)}{2}

x > ln(3) or x > 1.09861
