A = 289
That's the side s squared,
s² = 289
s = 17
In a square the perimeter is the sum of four equal sides
p = s + s + s + s = 4s = 4(17) = 68
Answer: 68 feet
Answer:
y = - 2x + 7
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 11) and (x₂, y₂ ) = (5, - 3)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 11), then
11 = 4 + c ⇒ c = 11 - 4 = 7
y = - 2x + 7 ← equation of line
Answer:
x=8 is a true solution of the radical equation
Step-by-step explanation:
we have

Solve for x
squared both sides

Convert to factored form

The solutions are x=2 and x=8
<u><em>Verify the solutions</em></u>
For x=2
Substitute in the original equation

----> is not true
therefore
x=2 is not a true solution of the radical equation
For x=8
Substitute in the original equation

----> is true
therefore
x=8 is a true solution of the radical equation
Answer:
hey ?
Step-by-step explanation:
Hello!
First you find the common difference in the sequence
6 - 12 = -6
0 - 6 = -6
The common difference is -6
We can now make the equation
-6(n - 1) + 12
we got the 12 because it is the first number in the sequence
Simplify
-6n + 6 + 12
Simplify
18 - 6n
The answer is B) an = 18 - 6n
Hope this helps!
