Find the domain of

A. x ≥ -1/6

B. x > 6

C. x ≥ -6

D. x ≥ 6

C (x ≥ -6)

Step-by-step explanation:

Algebraic:

The domain of is . When transformed 6 units to the left, it becomes

Graphically:

As shown in the attached graph, .

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
