Starting with 5^0 (since in PEMDAS, we have parenthesis, exponents, multiplication, division, addition, and subtraction, and exponents come before multiplication), we know that anything to the power of 0 equals 1. Therefore, 5^0=1. Next, for 2^1, anything to the power of 1 means it's that number, so 2^1=2. Note that for 2^3 (and for most exponents), however, it's 2 multiplied by itself 3 times, or 2*2*2=8. Since 5^0=1 and 2^1=2, 5^0*2^1=1*2=2

Answer:
41
Step-by-step explanation: u first expand (5x-2)²
to get 25x²-20x+4
then by comparing it to ax²+bx=c
u get a=25 b=-20 and c=4
the u evaluate a+c²
25+4²
=41
answer:
you can't simplify that
step-by-step explanation:
3/2- /2 isn't a proper equation, therefore it cannot be simplified
please let me know if the issue is that you forgot the numerator, and in the instance that this is the case please type in the comments the numerator and i'll gladly change my answer
have a nice day!
Answer:
Chuck's rate of travel = 63mph
Step-by-step explanation:
Given chuck travels 252 miles and dana travels 228 miles. Given that they both take same time to travel .
Let the travelling time be T.
Also given that the speed of chuck is 6mph greater than that of dana's.
let the speed of chuck be x. Now
Speed = 
x= 
Now for Dana's speed
x-6= 
When we divide both the equations we get
x=63mph
Answer:
