360 - 90 = 270
Plug in the two expressions
270 = (7x + 6) + (6x - 7) -> expand
270 = 42x^2 - 1 -> bring the one to the other side and add
271 = 42x^2 -> divide by 42
6.4 = x^2 -> find the square root
2.5 = x
Then solve both equations with x = 2.5 :^)

Answer:
Step-by-step explanation:
Step one- Find out how much it costs for one Lizard In this case, for four lizards it costs $47.88. To find the price for one lizard you divide 47.88 by four
$47.88/4Lizards=$11.97 per lizard.
Step two- Now that we have the price for one lizard, your question asks you how much for 6 lizards. We need to find that cost. To do so you multiply $11.97 by 6 for the lizards.
Your answer is $71.82

The c(t) equation, as you can see, is a quadratic equation, and thus its graph is a parabola, the leading term's coefficient is positive, so the parabola looks like the picture below
and the lowest point is at the vertex
c(t) reaches it's lowest point there
Answer:
94
Step-by-step explanation:
add 94, 75 and 83 to get 252, then divide by 3
