We are told that Tristan is planting a garden that's square shaped and its area is 64 square meters. Because 8 * 8 = 64, we have a square where each side is 8 meters along.
From an algebra point of view, where s is a side of the square,
s² = 64
s = 8 or s = -8 by taking square roots of both sides
s = 8 by discarding the -8 (lengths cannot be negative)
Now that we know a square's side we need its perimeter. Each side is the same, so a square's perimeter is four times a side.
4 * 8 = 32, which is our perimeter.
Therefore 32m² of material are needed.
Hi!
<h3>To do this, put the values in the equation. </h3>
-2 * 2 + 4 * 5 = -16
<h3>Solve</h3>
-4 + 20 = -16
<u>16 = -16</u>
<h2>(2,5) is not a solution of -2x+4y=-16</h2>
Hope this helps! :)

Answer:
x = 63
Step-by-step explanation:
Simplifying
x + -18 = 45
Reorder the terms:
-18 + x = 45
Solving
-18 + x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + x = 45 + 18
Combine like terms: -18 + 18 = 0
0 + x = 45 + 18
x = 45 + 18
Combine like terms: 45 + 18 = 63
x = 63
Simplifying
x = 63
The probability of randomly selecting a tree or a flower is 8/15.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of randomly selecting a tree or a flower = (number of trees / total number of flash cards) + (number of flowers / total number of flash cards)
8/30 + 8/30 = 16/30 = 8/15

PEMDAS
first simplify in the parenthasees so
(34 times 14)=476
second parenthasees
42-(20 times 16))
wait, there is second parenthases within so
(20 times 16)=320
(42-320)=-278
now divide
476/-278=-238/139= aprox -1.71223
