Answer: (x-2) inches.
The question asks for length in square inches. There is no such thing. It should read in inches. Since it is a square frame, we can take the square root of (x^2-4x+4), which is (x-4). This is in incnes
Step-by-step explanation:
(x-4)*(x-4) = x^2-4x+4
Answer:
The length of diagonal d is 14.1421 cm
Step-by-step explanation:
We are given square
Length of side of square = 10 cm
We need to find the length of diagonal d
To find diagonal of square, the formula used is:

where s is length of side of square.
Putting values of s and finding length of diagonal of square

So, The length of diagonal d is 14.1421 cm
Answer:
y = - 3x + 21
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 4 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (7, 0 ) into the partial equation
0 = - 21 + c ⇒ c = 0 + 21 = 21
y = - 3x + 21 ← equation of parallel line
Relations are ordered pair sets (x,y) mapping a value to another value
the set of 1st components is called the domain
the set of 2nd components is called the range
