Answer:
P = 2n + 8m - 1
Step-by-step explanation:
A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.
If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.
The perimeter is the total length of all the sides.
The formula for the perimeter of a triangle is for each of the three sides.
Substitute each of the three sides.
brackets can be removed
rearrange equation according to like terms
collected the like terms by addition

12m,
Step-by-step explanation:
424.12inches squared
Step-by-step explanation:
Formula= pie X radius squared X height
3.14 times 9 times 15
The steepness of a slope is determined by the magnitude of the coefficient. Taking the absolute value of all of our numbers, 12 is the greatest in magnitude.
Therefore, the steepest slope is the slope with 12.
