4000
Step-by-step explanation:
Answer:
x=149
Step-by-step explanation:
pythagoras theorem dictates that a squared +b squared= c squared
in this case, c=x
51*51+140*140=x*x
2601+19600=x*x
22201=x*x
x=149
Answer:
Step-by-step explanation:
Let (2n-1) and (2n+1) be the consecutive, odd numbers.
(2n-1)(2n+1) = 143
4n² - 1 = 143
4n² = 144
n² = 36
n = 6
2n-1 = 11
2n+1 = 13
The numbers are 11 and 13.
Answer:
x = 15
Step-by-step explanation:
x/3 + 10 =15
Subtract 10 from each side
x/3+10-10 =15-10
x/3 = 5
Multiply each side by 3
x/3*3 = 5*3
x=15
Given:
The function is .
To find:
The function .
Solution:
We have,
Substitute f(x)=y.
Interchange x and y.
Divide both sides by 3.
Taking power 4 on both sides.
Subtract 7 from both sides.
Substitute .
Therefore, the correct option is C.
