Answer:
Step-by-step explanation:
20/100 * 5,120 = 1024
Number of cases in 2013 = 1024 + 5120 = 6,144 cases
X² <span>− 3x − 70=0
</span>x² + 7x - 10x − 70=0
x(x+7) - 10(x+7) = 0
(x+7)(x-10) = 0
x + 7 = 0 or x - 10 = 0
x = -7 x = 10
Answer: x=-7, x=10
122.5.
A=b x h/2. A=122.5 b=7
A x b=h
122.5 x 7 =122.5
Answer:

Step-by-step explanation:
Given the equation of the circle: 
We wish to express it in a Standard form:
We begin by re-arranging:

Next, divide the coefficient of x by 2, square it and add it to both sides.
Do the same for y.

Next, we factorize

This is the standard form.
