THIS IS EASY BUT PLS HELP A NIKA OUT

viktelen [127]

Answer:

32.4

Step-by-step explanation:

$- 7n = 7 \times - 4.8$

$m = - 1.2$

So -7n + m becomes

$( - 7 \times - 4.8) + - 1.2$

Which then can be simplified to

$33.6 + - 1.2$

And finally:

$33.6 - 1.2 = 32.4$

(2x+3)²=125 find x with full solution please

Schach [20]

Answer:

x = ± ( 5√5 - 3 ) / 2

Step-by-step explanation:

We are given the equation ( 2x + 3 )² = 125;

$( 2x + 3 )^{ 2 } = 125 - Take Square Root on Either Side,\\| 2x + 3 | = \sqrt{ 125 } - Simplify Square Root of 125,\\\\| 2x + 3 | = \sqrt{ 5 * 25 } - Simplify Further,\\| 2x + 3 | = 5\sqrt{ 5 } - Take | |,\\\\2x + 3 = 5\sqrt{ 5 } , and , 2x + 5 = - 5\sqrt{ 5 } - Algebra, \\2x = 5\sqrt{ 5 } - 3 , and , 2x = - 5\sqrt{ 5 } - 3 - Divide Either Side by 2\\\\x = ( 5\sqrt{ 5 } - 3 ) / 2, and , x = ( - 5\sqrt{ 5 } - 3 ) / 2\\Conclusion ; x = ( + / - 5\sqrt{ 5 } - 3 ) / 2$

Solution ; x = ± ( 5√5 - 3 ) / 2
