Answer:
48.2 cm
Step-by-step explanation:
The bottom side of the large triangle has length 78 cm.
The bottom side of the right triangle has length 78 cm/2 = 39 cm.
Now we use the Pythagorean theorem to find the vertical side, the spine.
39² + s² = 62²
s² = 3844 - 1521
s² = 2323
s = 48.2
Answer: 48.2 cm
your answer to that division problem is 35.9
Answer:
y = 3*(x^2) + 9x -30
Step-by-step explanation:
y=3(x+5)(x-2)
y = (3*x + 3*5) * (x - 2)
y = (3*x + 15) * (x - 2)
y = 3*x*x + 3*x*(-2) + 15*x + 15*(-2)
y = 3*(x^2) - 6x + 15x - 30
y = 3*(x^2) + 9x -30
