Answer:
Step-by-step explanation:
The tough part of this question is figuring out what to do with √(7^2). You could do it by expanding the square. √(7^2) = √49
Now what is the square root of 49? Is it not 7?
√49 = 7
7^6 * 7^1
7 ^(6 + 1)
7 ^ 7

Answer:
A
Step-by-step explanation:
This is from the definition of an inverse matrix. Always will be 1 when multiplied.
Answer:
A: The chord is perpendicular to the diameter
Proof:
CE=DE (definition of bisector)
Center O, so OC and OD are radii.
OC=OD.
OE=OE.
OCE=ODE (SSS)
angle OEC = angle OED (corresponding parts)
angle OEC and angle OED are supplementary
So angle OEC and angle OED are both right angles.
CD is perpendicular to OE
CD is perpendicular to AB
X is -2 when 7+x=5
So 3*-2+2=-6+2
The answer is -4
