Answer:
The value of c is 12.25
Step-by-step explanation:
we know that
A perfect square trinomial is of the form
In this problem we have
so
equate the equations
we have
the following equations
-----> equation A
and
-----> equation B
<u>Solve the equation A</u>
<u>Solve the equation B</u>
therefore
The value of c is 12.25
Answer:
$12.79
Step-by-step explanation:
$45 - $18.63 = $26.37
$26.37 - ($.47 x 2) = $26.37 - $.94 = $25.43
$25.43 - $12.64 = $12.79

Step-by-step explanation:
Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.
The width would be 9 inches. Here's how I got the answer:
Double 12
Subtract from total
Take your difference and divide by two.
That will give you the width.
