Answer:
Fiona is correct. Meghan is incorrect.
Step-by-step explanation:
An equation is a mathematical statement consisting of two sides and an equal sign equating those two sides. Each side comprises an <em>expression</em>. An equation is a statement because it claims the two expression equal. This may be true, or false, or true for only certain values of variable appearing in the expression. However, an equation is distinctly different from a simple expression.
Answer:
x = P/8
Step-by-step explanation:
The perimeter of the blueprint is given by the equation :
P = 8x
We need to solve the above equation for x.
Dividing both sides of the equation by 8.

Hence, the value of x is P/8
Answer:
Step-by-step explanation:
X^4 - 10X^2 + 9 =0 This factors. It just looks odd.
(x^2 - 1)(x^2 - 9) = 0
x^2 - 1 = (x + 1)(x - 1) = 0
x = 1 and x = - 1
x^2 - 9 = (x + 3)(x - 3) = 0
x = 3
x = -3
The correct answer is C (third one down).
