Hmm
(a+b)^2=(a+b)(a+b)=a^2+2ab+b^2
basically
for
ax^2+bx+c
it is a perfect trinomial when
b=2(√a)(√c)
remember to take both positive and negative roots into consideration
because
(a+b)^2=a^2+2ab+b^2 and
(a-b)^2=a^2-2ab+b^2
see each
first one
-70=2(9)(4)
-70=72
false
second
-90=2(8)(5)
-90=80
false
third
-72=(9)(4)
-72=72
false
but, the last one could be negative
(9x-4)^2 is factor
that is the answer
the answer is 81x^2-72x+16
The symptoms of depression and suicide are very similar, because most of the people that are depressed sometimes think about doing something to harm themselves. Plus depression causes them to stop eating, starts to be non social etc. The same goes for those who are having thoughts of suicide or have already done it.
In addition to the information given in the question,
the answer is going to depend on ...
-- the dimensions of the dice
-- the height of the box.
The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.
<h3>Linear model Equations</h3>
It follows from the task content that;
- The scientist starts with a sample of 30 bacteria cells, it follows that the intercept of the linear model is 30.
Additionally, since the number of bacteria cells increases by 50% every hour implies that the rate of change, slope of the equation is 0.5.
Hence, the required equation is; y = 0.5x + 30.

The only common context with Dilation and function is that they are both describing the equation. Dilation is actually a characteristic defining the translation or compression of the graph of a function. Wherein there is a common point or center point.
