Scalene triangle
because all sides are of a different length
Answer:
4 ft
7.2 ft
20 ft
Step-by-step explanation:
When the balloon is shot, x = 0.
y = -0.05(0)² + 0.8(0) + 4
y = 4
The balloon reaches the highest point at the vertex of the parabola.
x = -b / 2a
x = -0.8 / (2 × -0.05)
x = 8
y = -0.05(8)² + 0.8(8) + 4
y = 7.2
When the balloon lands, y = 0.
0 = -0.05x² + 0.8x + 4
0 = x² − 16x − 80
0 = (x + 4) (x − 20)
x = -4 or 20
Since x > 0, x = 20.
Help with what im so confused
Answer:
-2x - (-5 - 4x) = -5(2x - 7)
-2x + 5 - 4x = -5 * 2x - 5 * (-7)
-6x + 5 = -10x - 35
-6x + 5 + 10x = -10x - 35 + 10x
4x + 5 = -35
4x + 5 - 5 = -35 - 5
4x = -40
4x/4 = -40/4
x = 10
