Answer: It's not
Step-by-step explanation:
A perfect square is always 
, where 
.
Knowing this, we can square root 144x to get 12x. Square rooting 81 gets us 9. Unfortunately, if we multiply 12 and 9 together, then double it, we get 216, which is definitely not 200.
Therefore, the polynomial is not a perfect square.
Answer:
the measure of arc AB is 150°
Use the FOIL method
First 4x × -2x = -8x^2
Outside 4x × -5 = -20x
Inside 3 × -2x = -6x
Last 3 × -5 = -15
-8x^2 - 20x - 6x -15 =
Combine like terms
-8x^2 -26x -15
Answer:
(-340)/231
Step-by-step explanation:
Simplify the following:
((-34)/33)/(7/10)
Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:
(-34×10)/(33×7)
33×7 = 231:
(-34×10)/231
-34×10 = -340:
Answer: (-340)/231
