X+y+z=51
y=2z
z=9+x
subsitute those
x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6
sub back
z=9+x
z=9+6
z=15
y=2z
y=2(15)
y=30
the numbers are
6,30,15
Answer:
D. -2
Step-by-step explanation:
The zero of a function is always along the x-axis and in this case that's -2.
Hope this helps :)
Since the base is 4x4, and the height is 2, you'll use the 2 as the height of the netting and the 4 as the length. so, it will be 2x4 which is 8ft^2
Hello :
to complete the factorization <span>unit tiles are needed :
</span>"3 negative unit tiles" and "<span>4 positive unit tiles"because : -3 and 4 are roots for
x²-x-12
x²-x-12 = (x+3)(x-4)</span>
Divide both sides with -6 to then get 16=8-k. Then subtract 8 to both sides. to get 8=-k. Finally, divide both sides by -1 to get your answer, -8=k.
