question a is 80
question b 20 (is what I could find but not completely sure)
Answer:





Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
Answer:
(See explanation for further details)
Step-by-step explanation:
The expression is transformed into its standard form:



The function does not represent a circle, as radius is a positive number.
Surface Area of can (SA) = (2 · π · r²) + (2 · π · r · h)
296.73 = [2 · π · (4.5)²] + [2 · π · (4.5) · h]
296.73 = 40.5π + 9π · h
296.73 - 40.5π = 9π · h
(296.73 - 40.5π)/9π = h
169.5/28.27 = h
6 = h
Answer: 6 inches
So in order to determine the factors of the given expression above, here is the step by step process.
Firstly, we need to know the factors of -8 that when multiplied together will result it -8. So after, I have listed it, I found out that it is -2 and +4.
So let us check. So the factors for this would be (3x-2)(x+4). When you multiply these factors, the result would be <span>3x2 + 10x - 8. Hope this answer helps.</span>
