What are the zeros of the function graph the function. <br> y=x(x+5)(x+4)
SIZIF [17.4K]
<span>Zeroes are found by setting y = 0.

x(x+5)(x+4) = 0
>> x=0 OR x+5=0 OR x+4 = 0
>> x = 0, x = -5, x = -4

So the zeroes of this function are x = 0, -5, -4/

For the graph, check attached image file.</span>

What is the value of A? <br>5<br>5 1/3<br>6 2/3<br>7
Anna35 [415]
This is a neat little question. I don't think I've seen it before.
Step one 
=======
Find c
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5

Step 2
====
Set up your first equation for b^2
a^2 + 4^2 = b^2 from triangle XWY

Step 3
=====
Set up your second equation for b^2
25 +b^2 = (a + 3)^2 from triangle XWZ

Step 4
=====
Put the results of Step 2 into step 3 and solve
25 + a^2 + 16 = (a + 3)^2 Collect the like terms on the left.
41 + a^2 = (a + 3)^2 Expand the brackets on the right
41 + a^2 = a^2 + 6a + 9 Transfer the 9 to the left.
32 + a^2 = a^2 + 6a Subtract a^2 from both sides.
6a = 32 Divide by 6
a = 32 / 6
a = 5 2/6
a = 5 1/3
