Its B, because (x-7)(x+1)=x^2-6x-7.
Answer:
A
Step-by-step explanation:
We know that the growth of a linear function will always be constant. So, that eliminates B and C.
A quadratic function can be a function such as
, or
, etc.
An exponential function wouldn't be
, it would be
! Or
, or
, etc. Therefore, D is eliminated.
So, the answer is
and we're done!
Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is
