Answer:
0.07
Step-by-step explanation:
From the question, a given grid was divided into a definite number of squares with some of the squares shaded.
Total number of squares in the grid = 100
number of shaded squares in the grid = 7
Thus, 7 squares are shaded out of 100 square in the grid.
So that this can be expressed in fraction as;
= 
= 0.07
The decimal number of the squares represented is 0.07.
Answer:

or

Step-by-step explanation:
we have
f(3+√2 )=f(3− √2 )=0
so
x1=3+√2 and x2=3−√2 are the roots or x-intercepts of the quadratic equation
The quadratic equation in factored form is equal to

substitute

Find the value of the coefficient a
Remember that
f(1)=−8
so
For x=-1 -----> f(x)=-8
substitute

solve for a

apply difference of squares


therefore


simplify
Applying distributive property

Answer:
(0.91)^{20}(0.09)
Step-by-step explanation:
This one has zeros of -2 and -5 which can be put into binomials
(x+2)(x+5), FOIL this to get
x^2 + 7x + 10, which is option C.
