Answer:
We want to estimate:
We can rewrite this as:
And √2 is a notable value, we know that:
√2 ≈ 1.41
Then:
then:
is a really good estimation.
if instead:
"the square root of eight divided by two to the second power"
refers to:
is easier, we just can replace 2^2 = 4, then we get:
Is also a really good aproximation.
1500 divided by 3 is 500

Answer:
c= 7/3
Step-by-step explanation:
To solve for c:
Simplify the equation by moving all numbers to one side and variables to the other
-9c-4=-25
-9c= -25+4
-9c=-21
Now isolate c by dividing both sides by its coefficient (-9)
c= -21/-9
Since the (-) cancel out, this simplifies to:
c= 21/9
Now reduce the fraction by dividing the right hand side by a common value of 3:
c= 7/3
