Zero of 7 with a multiplicity of 3 means one factor is 
Zero of -1 with a multiplicity of 2 means one factor is 
Zero of 5 with a multiplicity of 1 means one factor is 
Multiplying, we get

That's already in factored form so we leave it here.
Answer:
The formula for calculating the width of the window is

Step-by-step explanation:
<u><em>The question in English is</em></u>
A rectangular window is l meters wide and h meters high, with a perimeter of 6 meters and an area of 2m². What is the formula for calculating the width of the window?
we know that
The perimeter of the window is equal to

we have

so

simplify
isolate the variable l
----> equation A
The area of the window is equal to

we have

so
----> equation B
substitute equation A in equation B
solve for w

The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
---> formula for calculating the width of the window
only the first statement is true - it is the experimental probability. the rest is incorrect: the ratio is not the number of trials; the theoretical probability should be 0.5 (for unbiased coins); ratio never represents a number of occurences.
Answer:
the y-intercept is 8 and the slope is -4/3 .
Step-by-step explanation:
Answer:
x = 5/6
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
