Answer:
angle x equals 25
Step-by-step explanation:
130 + 25 = 155
180 - 155 = 25
Triangles always add up to 180°
Answer:
x=2 and x=12
Step-by-step explanation:
|2x+1| = |3x-11|
2x+1 = 3x-11
2x = 3x-12
-x = -12
x = 12
2x+1 = -(3x-11)
2x+1 = -3x+11
5x+1 = 11
5x = 10
x = 2
Answer:
-16,-14,-12,-10
Step-by-step explanation:
Let the integers be x, x+2,x+4,x+6
ATQ,
x+x+2+x+4+x+6=-52
4x+12=-52
4x=-52-12
x=-64/4
x=-16
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.
