Will someone me with the 2 highlighted questions? i did them already but idk if they are correct.

14) x = 5,  and x = -5

16) x = 4 + √10 and x = 4 - √10

Step-by-step explanation:

14)

x^2 - 25 = 0

Add 25 to both sides

x^2 = 25

Take square root each side

x = 5,  and x = -5

16)

x^2 - 8x = -6

Add (-4)^2 to both sides

x^2 - 8x + (-4)^2 = -6 + (-4)^2

Simplifying

x^2 -  8x + 16 = - 6 + 16

(x - 4)^2 = 10

Take square root each side

x - 4 = + - √10

Add 4 to both sides

x = 4 + √10 and x = 4 - √10

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
