Equation:
----------------------------------------------------------------
y= -4x² <span>+ 16x - 7
</span>----------------------------------------------------------------
<span>Find x-intercept:
</span>----------------------------------------------------------------<span>
At x-intercept, y = 0
</span> -4x² + 16x - 7 = 0
(7 - 2x) (2x - 1) = 0
----------------------------------------------------------------
Apply zero product property:
----------------------------------------------------------------
(7 - 2x) = 0 or (2x - 1) = 0
x = 3.5 or x = 0.5
----------------------------------------------------------------
Answer: The x-intercept are (3.5, 0) and (0.5, 0).

Answer: y = 6</h3>
The triangle has a base of y and a height of 5. The area of the triangle is
area = (1/2)*base*height = 0.5*y*5 = 2.5y
which multiplies with the prism's depth 8 to get 2.5y*8 = 20y
The expression 20y represents the volume of the prism, which we are told is 120 cubic meters, so 20y = 120 solves to y = 6 after dividing both sides by 20.
Step-by-step explanation:
Earth = 1trip
Mars = ½trip
If,
Mars = 1trip
Earth = ?
If more, less divides,
