Answer:
The area of square in terms of x = 16x² -24x + 9
Step-by-step explanation:
It is stated in the question that the length of a square = 4x - 3
Formula to find the area of the square is
Area = length²
Area = ( 4x - 3 )²
by using ( a - b )² = a² + b² - 2ab
here a = 4x and b = -3
So,
(4x)² + (-3)² - 2(4x)(3)
16x² + 9 - 2(12x)
16x² + 9 - 24x
16x² -24x + 9
The area of square in terms of x = 16x² -24x + 9
Answer:
The sum of 2 and the quotient of 3 and y
Step-by-step explanation:
The expression 2 + 3/y without any parentheses is evaluated as ...
2 + (3/y)
which is a sum. The first contributor to the sum is 2, and the second contributor is the quotient of 3 and y. (Usually, "the quotient of "a" and "b" means "a/b".)
Hence the answer shown above is a good description of the expression.
Hey there! :D
Plug in x for 2.
4x= 4(2)
x^4= (2^4)
Evaluate.
4x= 8 2^4= 16
Now, subtract the difference.
16-8= 4
The difference is 4.
I hope this helps!

ANSWER
The car moves at 32 mi/hr
EXPLANATION
This question is asking us to determine how fast is a train that makes 330 mile trip in 4 hours.
This is the same as calculating the speed of the train:
Speed = distance covered/time taken
The distance covered is 330 mile
The time taken is 4 hours.
Speed =330/4 =82.5 mi/hr
