Hello!
To find the surface area of a cube you use the equation

a is a side length
Put in the values you know

Square the number
6 * 121 = 726
The answer is

Hope this helps!
The irrational number that can be added to pi to get a rational sum is PI.
4 terms, degree of 2
The terms is the amount of “numbers” you have, which is 4
The degree is the highest power, which is x^2
Well the formula is : b1+b2/2 (h)
so the height would be solved as :
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9) *reciprocal*
h = (27) / (9)
h = 3
Answer:
(3x - 2)(3x + 2)
Step-by-step explanation:
9x² - 4 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
9x² - 4
= (3x)² - 2²
= (3x - 2)(3x + 2) ← in factored form
