The correct answer of the given question above would be option D. The thing that must happen for historians to consider a particular time in a civilization as a classical period is that, the civilization must make extraordinary achievements in areas such as art and science.
Answer:
angle A is 63 degrees,
angle B is 57 degrees
Step-by-step explanation:
first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:
2x+3+2x-3=120
now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:
4x=120
now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.
substitute the 30 into the x in the original equation, and this becomes:
60+3+60-3=120
63+57=120
thus, angle A is 63 degrees, and angle b is 57 degrees.
Answer:
x intercepts there are three and y intercept in 0
Step-by-step explanation:
so f(x)=a(0+3)(x-2)^2(x-2)
-2=a(3)(4)(-2)
-2=a(-10)
a=5
rewrite
f(x)=5(x+3)(x-2)^2(x-2)

"x" represents an unknown number, we know that 70% of x equals 63.
To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:
So the 70% of x can be calculated as:
You can simplify this expression by solving the division
Then the expression that shows you the relationship is
Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7
The value of x is 90
