Step-by-step explanation:
Given a parallelogram with points
X(4, 0)
W(0, -1)
Y(3, -2)
Z(-1, -3)
We want to find the perimeter, perimeter is the total sum of the lengths
So, we need to find the length of the sides using distance between two points
D = √(x2-x1)² + (y2-y1)²
So, applying this
WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17
XY = √(4-3)² + (0--2)² = √(1+4) = √5
Since the opposite sides of a parallelogram are equal, we don't need to find the other length
Then,
Perimeter = 2(WX + XY)
Perimeter = 2(√17 + √5)
Perimeter = 2√17 + 2√5
The correct answer is B.
Answer:
D. a−b=10 a=3b+4
Step-by-step explanation:
Difference between a and b means to subtract b from a
We have,
a-b=10
a is 4 more than 3 times b
4 more than means to add 4
3 times b means to multiply b by 3
Therefore, a=3 times b + 4
a=3b+4
a - b=10; a=3b+4
