57. If you draw a diagram and make a right traveler with the Jacques, the base of the cliff, and the top of the cliff, it should be obvious that tan(35 degrees) = (cliff height)/1200m. Solving, cliff height = 1200 * tan(35 deg) = 840 meters.

Original price = 480
After 20% off, price = 480 - 0.20 * 480 = 384
After 7.5% tax, price = 384 + 0.075 * 384 = 412.80, which is the total desired.
Here’s the graph of y=2x+7 where a point on the graph is (-2,3)
Short answer yes its true
Answer:
2x² + 5x - 3
Step-by-step explanation:
(x + 3)(2x - 1)
Use FOIL
First terms
x * 2x = 2x²
Outer terms
x * -1 = -x
Inner terms
3 * 2x = 6x
Last terms
3 * -1 = -3
---------------------
FOIL
2x² - x + 6x - 3
Combine like terms
2x² + 5x - 3
One solution. Hope this helps!
