-(-7y + 12) = 7y - 12
u are distributing the -sign through the parenthesis...so u take the number outside of the parenthesis (and if it just a sign, the number is 1)...and u multiply it by everything in the parenthesis.
-1(-7y + 12) = -1 * -7y + (-1) * 12 = 7y + (-12) = 7y - 12
The diameter of the cell model according to the taks content is; 14in.
<h3>Diameter of the cell model</h3>
Volume of paint = 615.44 square inches
π = 3.14
Volume of a sphere = 4πr²
615.44 = 4 × 3.14 × r²
615.44 = 12.56/r²
r² = 615.44 ÷ 12.56
r² = 49
r = 7
Hence, the diameter of the cell is; 2 × r = 2 × 7 = 14in.

Sand Dune Landforms
Sand dunes (both active and stabilized by vegetation) can be found along beaches, and in arid or semi-arid regions. Dunes are mounds of loose sand created by wind and are the most well known aeolian features
(2x + 3) + (x+1) + (3x-10) = 180
6x - 6 = 180
6x = 186
x= 31
