S = 7x^2....divide both sides by 7
1/7s (same as s/7) = x^2...now take sqrt of both sides
(+ - ) sqrt 1/7s = x
Answer:
X=4
Step-by-step explanation:
The angle CA equals 4. The angle AB are equal to the angle CA therfore, the outcome of x=4.
Step-by-step explanation:
Using distance formula,
Let the distance between point E and F = ef,

Answer: 243
Step-by-step explanation:
We have the expression

Note that the expression depends on 3 variables
a, b and c
in this case we want to evaluate the expression for

Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4
So we have

Now simplify the expression


The answer is 243
