Answer:
(-13,12)
Step-by-step explanation:
So, first, you make two separate equations.
4 + x = -9 (The 4 is from Q and the -9 is from V)
-11 + y = 1 (The -11 is from Q and the 1 is from V)
Then, you subtract 4 from both sides on the first one, and subtract -11 from both sides on the second one.
You should get:
x = -13
y = 12
46
You need just substitute values of x and y, and calculate.
24x - 13y = 24*3 - 13*2 = 72 - 26 = 46
x = 35
Since m1=m2 :
19 ft
The perimeter of a rectangle is given by ...
P = 2(L +W)
Filling in the given values, we have ...
78 = 2(20 +W)
39 = 20 +W . . . . . divide by 2
19 = W . . . . . . . . subtract 20
The width of the rectangular pen is 19 feet.
