Answer:
Perimeter = 28.8 inch
Step-by-step explanation:
Step 1: Change given centimeters into inches according to the scale
2.5 / .5 = 5 <--- length in inches
4.7 / .5 = 9.4 <--- width in inches
^^^This is the same thing as multiplying 2.5 cm and 4.7 cm by two. You could also reword the scale to be 1 cm = 2 inch if it makes more sense for you
Step 2: Find the perimeter using the formula: P = 2L + 2W
2 (5) + 2(9.4)
10 + 18.8
<span>f(x) = x^2 - 12x + 7
First, separate the first two terms from the constant
f(x) = (x^2 - 12x) + 7
Next, half the coefficient of second term in the parenthesis (12x) and square the result. Make sure to subtract outside the parenthesis what you added inside so that the equation stays equal.
f(x) = (x^2 - 12x + 36) + 7 - 36
f(x) = </span><span>(x^2 - 12x + 36) - 29
Now, just factor the trinomial inside the parenthesis, lemme know in a comment if you don't know how to do this and I'll explain.
f(x) = (x(x - 6) -6(x - 6)) - 29
f(x) = (x - 6)^2 - 29
The polynomial is now in vertex form, and the value of a, as you can see, is 6.
