2. the quadratic equation az^2 + bz + c = 0 would be easy to solve if b = 0. why? the following steps reduce the solution of a general quadratic to this case. you get to carry them out and rediscover the quadratic formula (a) let d be a complex number to be determined. make the change of variables z = w-d in the quadratic equation a: 2 +bs + c = 0 to obtain a quadratic equation for w (b) what choice of denables you to reduce the equation for uw to one you know how to solve?

5x+2x=49

7x=49

x=7. 35 apples

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

answer: the correct answer is -32
