Since we are asked about the distance from corner to corner,
we are to find the hypotenuse. So using the hypotenuse formula:
c^2 = a^2 + b^2
c^2 = 960^2 + 750^2
c^2 = 1,484,100
c = 1,218.24 m
Hence the distance from corner to corner is about 1218
meters.
F(x) = 3(x^2 - 8x + 16) +1/3 -48
r = 16
s = -48
Answer:
x = 1
Step-by-step explanation:
For this problem, we are simply solving for x, and analyzing the results of the two students. First let's solve for x ourselves:
5 ( x + 3 ) = 20
5 ( x + 3 ) * ( 1 / 5 ) = 20 * ( 1 / 5)
x + 3 = 4
x + 3 + -3 = 4 + -3
x = 1
So we know the solution for this equation is x = 1.
Now let's look at the solutions of the two students. Alex's "divide first" way is correct since it follows the proper order of operations. The order of operations are simply a way in which to simplify problems correctly. Here is the order of things to handle first:
Parenthesis --> Exponents --> Multiplication (Division) --> Addition (Subtraction)
Looking at Morgan's "subtract first" way, we know that he has violated the order of operations. For this specific problem, the distributive property of multiplication is ignored in Morgan's approach, resulting in an incorrect answer.
I hope this helps.
Cheers.
8x-12=5x+15
add 12 to both sides
8x=5x+27
subtract 5x from both sides
3x=27
divide by 3
x=9
