Answer:
goals scored is 15
Step-by-step explanation:
As 60 goals scored in total and goaladinho scored a quarter of them so 60÷4=15
Answer:
1/c^102
Step-by-step explanation:
C^-24 * c^9 * c^-87
When we multiply exponents with the same base, we add the exponents
c^(-24+9+-87)
c^(-102)
We know that a^-b = 1/a^b
1/c^102
Since 4 is half of the number 8, the simplest form of that would be 1/2
~1/2 is the same as 4/8
Answer:
this is a trick question. The answer would be 67.
Step-by-step explanation:
It is 67 because 16 dollars he made last week. BUT it says "and now has 67 dollars." that "and" meaning total sum. Maybe I'm wrong but this is my guess.
Answer:
A.
Step-by-step explanation:
Take a look at what happens when squaring either of these...
Notice a couple of patterns.
1. The last term has a positive coefficient. That rules out answer choices C and D.
2. The coefficient of the middle term is either 
. So what are <em>a</em> and <em>b</em>? <em>a</em> is the square root of the x^2 term and <em>b</em> is the square root of the y^2 term.
The middle coefficient needs to be either +30 or -30. The answer is choice A.
