Answer:
The answer to your question is 8/3 u²
Step-by-step explanation:
Data
length of the side = 2/3
Surface area = ?
Process
1.- Calculate the area of one face
Area = side x side
-Substitution
Area = 2/3 x 2/3
-Result
Area = 4/9
2.- Calculate the area of the cube (a cube has 6 faces)
Surface area = 4/9 x 6
= 24/9
-Simplification
Surface area = 8/3 u²
To solve for the quadratic equation 9x² = 4, we need to recall that the difference between two square can be expressed as the product of their sum and difference or (a² - b²) = (a + b)(a - b).
Thus, we have
9x² = 4
9x² - 4 = 0
(3x)² - (2)² = 0
(3x + 2)(3x - 2) = 0
We now have two linear equations:
3x + 2 = 0 | 3x - 2 = 0
3x = -2 | 3x = 2
x = -2/3 | x = 2/3
Thus, x = +2/3 and -2/3.<span>

U have to find the percentage that doesn't have gym memberships between 216. then divide by 8 and then multiply by 5
Answer:
Choice D. a - b = 12 and a = 3b + 5
Step-by-step explanation:
so |a - b| = 12
a = 3b + 5
3b + 5 - b = 12
2b + 5 = 12
b = 7/2
what if b - a = 12
b - 3b - 5 = 12
-2b = 17
b < 0 no.
choice A. works so does choice D.)
