Answer:
Step-by-step explanation:
(10 - x^2)/b = b/2
Cross multiply
2(10 - x^2) = b^2
20 - 2x^2 = b^2
2x^2 = 20 - b^2
Dividing through by 2
x^2 = (20 - b^2)/2
√x^2 = √(20 - b^2)/2
x = √(20 - b^2)/2
Answer:
All real numbers
Step-by-step explanation:
21 - 7x = 7(3 - x)
21 - 7x = 21 - 7x
Since both sides of the equation are equal, the answer is all real numbers.
