Answer:
Therefore the two values required are 2.08 and -11.08.
Step-by-step explanation:
i) f(x) = + 10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.
ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.
This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.
∴ + 10x -12 = 0 ⇒ x = (-10 ±
) ÷ 2
= (-10 ± 12.166)÷2 = 2.08, -11.08
Therefore the two values required are 2.08 and -11.08
Answer:
20 yd²
Step-by-step explanation:
This problem is really easy once you break it down!
First, find the area of the triangle.
b = 5 + 3 = 8
h = 4 + 4 = 8
Now find the area of the square.
The last step is to subtract.
Area of triangle - area of rectangle =
32 - 12 = 20
20 yd²
Hope this helped! :)
without changing units, since we can have a lbs:oz ratio, and that's perfectly fine
