find the perimeter of a triangle with sides 15 inches, 15 inches, and 21 inches length
To find the perimeter of a triangle we add all the sides of the triangle
The length of the sides of the triangle are given as 15 inches, 15 inches, and 21 inches
Perimeter of a triangle =
15 inches + 15 inches + 21 inches = 51 inches
So 51 inches is the perimeter
Answer:
the third selection is corret
Step-by-step explanation:
Ax + by + c = 0, k = - a/b.
so The slope of the first line =
,
the slope of the second line =
;
So these two lines are parallel and they don't intersect

Answer:
≈ 39.7ft
Step-by-step explanation:
The Pythagorean theorem:

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)
First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.


To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

≈ 39.7ft
Answer:
The parts it includes is everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Examples of ways that we use algebra are finding the distance, perimeter of an area, volume, determining the cost of something, renting something, time relationships, pricing options for something you want to buy, and more.
