Answer:
x = 2, y = 5
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, thus
PT = TR and QT = TS
Substitute in values
y = 2x + 1 → (1)
3y = 3x + 9 → (2)
Substitute y = 2x + 1 into (2)
3(2x + 1) = 3x + 9
6x + 3 = 3x + 9 ( subtract 3x from both sides )
3x + 3 = 9 ( subtract 3 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into (1)
y = 2(2) + 1 = 4 + 1 = 5
Volume=(4/3)pi(r^3)
radius=1/2diameter
d=36
radius=1/2 36
radius=18
subsitute
volume=4/3 pi 18^3
volume=4/3 pi 5832
volume=23328/3 pi
volume=7776pi
aprox pi to 3.14
volume=7776 times 3.14
volume=24416.64
answer is 24416.64 yd^3
I honestly don’t know because I honestly don’t know
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
