Parallelogram opposites side theorem which states that If a quadrilateral is a parallelogram , then it’s opposite sides are congruent
Answer:
Step-by-step explanation:
3x +2y = 13 -----------------(i)
x + 2y = 7 ----------------(ii)
Multiply the equation (ii) by (-1) and then add.
(i) 3x + 2y = 13
(ii)*(-1) <u>-x - 2y = -7 </u> {Now, add and y will be eliminated}
2x = 6
x = 6/2
x = 3
Plug in x = 3 in equation (i)
3*3 + 2y = 13
9 + 2y = 13
2y= 13 - 9
2y = 4
y = 4/2
y = 2
I believe the answer to be 125 3*, theres a chance im wrong as I am unsure of this, I only know how to get the value which is 5.
P = 2(L + W)
P = 114
W = 23
114 = 2(L + 23)
114 = 2L + 46
114 - 46 = 2L
68 = 2L
68/2 = L
34 = L <=== so the length is 34 ft
The product of the slopes would be -1 because the slopes of two lines that are perpendicular are opposite reciprocals (ex. 2 and -1/2 multiplied together would be -1)
