Solve these equations:<br> (a) x squared= 49<br> (b) x squared – 7 = 29<br> (c) 4x squared = 64

Lunna [17]

A.
$x^2=49 \\
\sqrt{x^2}=\sqrt{49} \\
|x|=7 \\
x=-7 \ \lor \ x=7 \\
\boxed{x=-7 \hbox{ or } x=7}$

b.
$x^2-7=29 \ \ \ |+7 \\
x^2=36 \\
\sqrt{x^2}=\sqrt{36} \\
|x|=6 \\
x=-6 \ \lor \ x=6 \\
\boxed{x=-6 \hbox{ or } x=6}$

c.
$4x^2=64 \ \ \ |\div 4 \\
x^2=16 \\
\sqrt{x^2}=\sqrt{16} \\
|x|=4 \\
x=-4 \ \lor \ x=4 \\
\boxed{x=-4 \hbox{ or } x=4}$

This my last one help

Lerok [7]

Answer:

A2 = 120

A3 = 60

A5 = 60

A6 = 120

Step-by-step explanation:

Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.

Angle 1 and 3 are vertical angles, which are always the same measure.

Angle 5 is alternate interior angles with 3, which means it is also 60.

Angle 6 is alternate interior angles with 4, which means it is 120.
