Which value is needed to create a perfect square trinomial from the expression x2 + 8x +

Explanation:

A perfect square is an expression in the form

which can be rewritten in a trinomial form:

(1)

In this problem, we have the following trinomial:

(2)

with C unknown. By comparing (1) and (2), we see that

from the first equation, we find

and substituting into the second one, we find

So, the perfect square trinomial form is

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
