Just plug it in:
c & d = c² + d² - 4
2 & 1 = 1² + 2² - 4
= 1 + 4 - 4 = 1
Answer: 277/12
Step-by-step explanation:
Use the order of operations or pemdas (parenthesis, exponents, multiplication, division, addition, subtraction) to solve this equation:
3 / 6^2 +7 x 4 - 5
there are no parenthesis, so exponents
= 3 / 36 + 7 x 4 - 5
now multiplication and division(from left to right)
= 3 / 36 + 7 x 4 - 5
= 1/12 + 28 - 5
addition and subtraction are next(it doesn't matter the order in this case):
1/12 + 23
= 1/12 + 276/12
= 277/12
i hope this helps
Answer:
Yes it does
Step-by-step explanation:
We can rewrite the original equation x-y⁴ =1 in terms of y as a function of x
We can rewrite
x-y⁴ =1
as
-y⁴ = 1-x (subtract x from both sides)
Multiplying by -1 both sides
y⁴ = x - 1
Taking the 4th root
which is y as a function f(x)
the answer is 25 because u can see that 1/2 is shaded, the sides times together are 50 and 50 divided by 2 is 25
