The answer is d= -2an+2s/n^2-n
That answer should be in a fraction form.
Answer:
x=5, y=-2. (5, -2).
Step-by-step explanation:
2x+3y=4
3x+4y=7
----------------
3(2x+3y)=3(4)
-2(3x+4y)=-2(7)
----------------------
6x+9y=12
-6x-8y=-14
-----------------
y=-2
2x+3(-2)=4
2x-6=4
2x=4+6
2x=10
x=10/2
x=5
Answer:
AE = 60 units
Step-by-step explanation:
GE is one third the length of AE so...
GE = 1/3(AE)
20 = 1/3x
3(20) = (1/3x)3/1
60 = x
x = 60
AE = 60 units
