Answer:

x > -3

Step-by-step explanation:

- 4x - 10 < 2

+ 10 < + 10

- 4x < 12

-4 -4

x > -3

I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...

The length of Side C D is 11 inches and the length of Side C F is 11 StartRoot 3 EndRoot inches. What is the length of Side D F?

11111nata11111 [884]

Answer:

DF^2=DH^2+HF^2

DF=√DH^2+HF^2

DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}

DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}

DF=√2*121

DF=√242

DF=15.555

THEREFORE,OPTION B..

Lets Do

$\\ \sf\longmapsto p = 2(l + w) \\ \\ \sf\longmapsto l + w = \frac{p}{2} \\ \\ \sf\longmapsto w = \frac{p}{2} - l \\ \\ \sf\longmapsto \boxed{ \bf \: w = \frac{p - 2l}{2} }$

(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
