The correct answer is 3, it is irrational and equal to 5\sqrt{2}.

The first step is to figure out the answer, then we can deduct whether it is rational or not, giving us our answer. To solve this, we first need to simplify \sqrt{32}. \sqrt{32} is equal to \sqrt{2 * 2 * 2 * 2 * 2}, which is equal to 4\sqrt{2}. Now our expression is 4\sqrt{2} + \sqrt{2}. This simplifies to 5\sqrt{2}. Since this expression has a square root, it is irrational, and since the result is 5\sqrt{2}, the answer is 3).

What are the zeros of the quadratic function f(x)=2x^2+8x-3
Nezavi [6.7K]

Answer:

-2 +/-  [(sqrt 88)/ 4]

or

0.35, -4.35 to the nearest hundredth.

Step-by-step explanation:

2x^2 + 8x - 3 = 0

Using the quadratic formula:

x = [ -8 +/- sqrt (8^2 - 4*2*-3) ] / 4

=  -2 +/-  (sqrt 88)/ 4

G. The shape would be similar since dilation at the origin is just a translation and a translation doesn't affect the shape's size or shape.

h. They will still be similar because adding length to each side will just make the shape larger, and if the shape hasn't changed (which it hasn't) it will remain similar.

I. This is simple, just write an equation of the changes you could do the shape and it would be similar. You would have to explain how many you should move and from which sides (should be all sides). It is better for you to do this because there are millions of possible equations, and if you use the same one then it might be striked.
