1 yard = 3 feet
4 yards = 3 × 4 = 12 feet
13 feet is greater than 4 yards
Answer:
48.2
Step-by-step explanation:
√(x2-x1)²+(y2-y1)²
√(15.3-59.5)² +(14.9-34.2)²
√(-44.2)² + (-19.3)²
√1953.64+372.49
√2326.13
48.2
all the sides of the triangle are the same because this is equilateral. this means:
(21 - x) = (2x - 3) = (x + 5)
Let's take (x+5) and (2x - 3)
x + 5 = 2x - 3 subtract x from both sides
5 = x -3 add 3 to both sides
8 = x you can rearrange this to x=8
Now it's the fun part! SUBSTITUTION! :D (sarcasm)
<u>BUT WAIT</u> Remember, all of the sides are equal to one another! That means we only have to solve for one side!
Let's do the top side. 21 - 8 = 13
Since there are 3 sides in a triangle, we can easily multiply the 13 by 3
13 x 3 = 39 The perimeter is 39 inches
Answer:
B $6.50
Step-by-step explanation:
We need to find the slope
This is given by
m = (y2-y1)/(x2-x1)
=(32.5 - 13)/(5-2)
=19.5/3
= 6.5
