False. You can pick any two numbers, but not the same number, to show its false. try it
Descending order for a polynomial means from highest value of exponent to the lowest value of exponent.
If you observe the options you can see that polynomial shown in option A is only listed in descending order i.e. starting from a maximum exponent of x and then moving towards lower exponents of x.
So answer to this question is option A
A. x∧2+(x+20∧2=150∧2 is correct.
because you need to plug the numbers into the pathagoreum theorum which is
a∧2+b∧2=c∧2
150 is our c because it is the side right accross from the right angle.
which number is a and which number is b does not matter.
x is the distance north so we can assign that to a and the distace east is north plus 20 so we can assign b to x+20.
Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
Answer:
1/25
Step-by-step explanation:
1 m = 100 cm
4m x 100 = 400 cm
If it is 16 cm long, then the scale factor is 16/400, which simplifies to 1/25.
