180 divided by 3 = 60
60 x 5 = 300

Perimeter of a square: side length * 4, since squares have equal side lengths
Take 2x - 3 for the side length and plug it into the formula.
(2x - 3) * 4 can be rewritten as 4(2x - 3)
Distribute 4 inside the parentheses.
8x - 12 = perimeter of the square
Answer:
<h3> To find x you need to divide polygon into triangles</h3><h3>The formula
: "the sum of exterior angles=360°" is false for concaved polygons</h3>
Step-by-step explanation:
α = 180° - 135° = 45°
β = 180° - 120° = 60°
γ = 180° - 60° = 120°
δ = 180° - x
ε = 180° - 80° = 100°
If we divide the pentagon into five triangles then:
5•180° = α + β + γ + δ + ε + 4x
900° = 45° + 60° + 120° + x + 100° + 4x
900° = 325° + 5x
5x = 575°
x = 115°
60° + 120° + 135° + 80° + 115° = 510° ≠ 360°
Answer:
B
Step-by-step explanation:
Since G(x) =F(x-6)-3
So on the x-axis it will shift - 6 units so to the left and - 3 units on the y-axis then 3 units down.
