Someone help me please ASAP

3. 45, 4. 24

Step-by-step explanation:

use formula: hypotenuse²= side² + other side ²

3.

x²= 27²+36² calculate the squares then add

x²=2025 square root both sides

x= √2025= 45

4.

25²= x²+7² isolate the vaiable by subtracting 7² from both sides

25²-7² = x² square then subtract

576 =x² square root both sides

24=x

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
