When you want to increase percentage, you divide the percentage by 100 and add it to 1. When you want to decrease, you divide the percentage by 100 and take it away from 1.
Therefore, I think:
a) 429 X 1.31 = 561.99
b) 345 X 0.88 = 303.6
The equation of a straight line in "standard form" resembles Ax + By + C = 0.
Starting with y − 3 = 1/3(x − 6) (which is the equation of a line in point-slope form), remove the fractional coefficient 1/3 by multiplying both sides of this equation by 3:
3y - 9 = x - 6.
We want all terms except for 0 to appear on one side of this equation. Subtract 3y from both sides, obtaining:
-9 = 1x - 3y - 6
Finally, add 9 to both sides, obtaining:
0 = 1x - 3y + 3
This result has the form Ax + By + C = 0, and is thus in standard form.

Answer:
287 in²
Step-by-step explanation:
The figure given is a combination of a cube and a rectangular prism. The formula for the volume of a rectangular prism is:
SA = 2(ab) + 2(ac) + 2(bc), where 'a', 'b' and 'c' are the measures of the prism.
The formula for the volume of a cube is:
SA = 6s², where 's' is the measure of the side of a cube
Prism: SA = 2(3*3) + 2(3*12) + 2(3*12) = 18 + 72 + 72 = 162 in²
Cube: SA = 6(5)² = 150 in²
Since the prism is stacked on top of one of the sides of the cube, you can subtract one of the sides since it is overlapping:
150 - 25 = 125 in²
total surface area: 125 + 162 = 287 in²
