Answer:

D, E

Step-by-step explanation:

(4x - 1) ^2 = 11 => (take square roots of both sides)

4x - 1 = +\- sqrt(11) => (Add 1 to both sides)

4x - 1 + 1 = 1 +\-sqrt(11) =>

4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)

x = ( 1 +\- sqrt(11) ) /4

Which are choices D and E

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.
