So
lets say we have
a/b=2a/2b
we know that if we invert one and multiply it by the other (divide them), we get 1 because a/a=1 where a=a
so
2/3 and 4/6 are equivelent because if you divide them we get 12/12=1
2/3 and 8/12 are equivilent because if you divide them we get 24/24=1
and sinde 2/3=4/6 and 2/3=8/12, 2/3=4/6=8/12
they are equivlent
Prime for 2 digit odd number: 13 , 11 , 17, etc
Odd number that is composite: 39, 25, 15, etc
Hope this helps
Answer:
729/5 • x^3 • y^20 • z^11
Step-by-step explanation:
Answer:
500
Step-by-step explanation:
r = 5
r³ = 125
V = (4/3)pi(r³)
pi = 3
V = (4/3)3(125)
/3 and x3 cancel
V = 4 x 125
V = 500
Answer:
f(-1) = 2
Step-by-step explanation:
To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).
f(x)=x²-3x-2 becomes
f(-1)=(-1)² - 3(-1) -2, or
f(-1) = 1 + 3 - 2, or
f(-1) = 2
