The complete factorization of the equation 81x² - 100 is; (9x - 10)(9x + 10)
<h3>How to factorize quadratic equations?</h3>
We are given the quadratic equation;
81x² - 100
Now, according to quadratic identities, we know that;
(a + b) * (a - b) = a² - b²
Now, our equation can also be expressed as;
81x² - 100 = 9²x² - 10²
Thus, applying the quadratic identity gives us;
(9x + 10)(9x - 10)

Means solve for y=mx+b form
so
expand/distribute
y-5=3x+3
add 5 to both sides
y=3x+8
Answer:no it’s 11/10
Step-by-step explanation:
First reduce the fraction so your equation looks like this:
2/27=x/36
Now cross multiply to simplify
72=27x
Now change sides
27x=72
Now divide both sides by 27
X= 8/3
Now you are left with your answer:
x= 8/3

Answer:
80.7 inches
Step-by-step explanation:
circumference = 2 * pi * r
2 * pi * r = 507 inches
r = (507 inches)/(2 * pi)
r = (507 inches)/(2 * 3.14159)
r = (507 inches)/(6.2832)
r = 80.7 inches
