Which of the following is equivalent to 6.32 x 10-*3?
In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.
The exponent is negative so you move to the left:

=
Therefore 6.32*10^-3 is equivalent too (c) .00632
Answer:
(x-12) (x+12)
Step-by-step explanation:
If you factor it out since both are perfect squares you would place an x on each side and then find the square root of 144, which is 12 and put a positive and a negative in each parenthesis.
angle1 = 4y - 9°
angle2 = 40°
angle3 = 5y°
Angle sum property
180° = angle1 + angle2 + angle3
Therefore,
180 = (4y - 9) + 40 + 5y
180 = 4y - 9 + 40 + 5y
180 = 9y + 31
180 - 31 = 9y
149 = 9y
149/9 = y
Your answer is D.
The polygon won't change shape or size, just its position.
