Answer:
if its on a coordinate plane the formula would be:
√(2x-1x)²+(2y-1y)²
Step-by-step explanation:
so if the coordinates were
A= (-3,2)
B= (4,2)
C= (4,-1)
D= (-3,-1)
for A to B it would be
√(4 - (-3)² + (2-2)²
√(7)² + (0)²
√(7·7) + (0·0)
√49+0
√49
or
7
I hope the explanation helped
Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
Answer:
m<7 = 61
Step-by-step explanation:
These angles (<7, and <8) are adjacent to each other (they are next to each other), therefore they are supplementary (add up to 180).
180 - 119 = m<7
