Answer:
Garden Trees Number
Redbud 2
Magnolia 3
Snowbell 1
Maple 4
Step-by-step explanation:
If the first mark is labeled Redbud and has 2 dots then it has 2 trees.
If the second mark is labeled Mangolia and has 3 dots then it has 3 trees.
If the third mark is labeled Snowbell and has 1 dot then it has 1 tree.
If the fourth mark is labeled Maple and has 4 dots then it has 4 trees.
7/10 times 3/6 is 21/60 just multiply a cross
Answer:
Step-by-step explanation:
3(x-2)(x-2)-8=5
3[x^2-4x+4]-8-5=0
3x^2-12x+12-13=0
3x^2-12x-1=0
use the quadratic formula to find x { -b+-sqrt(b^2-4ac) } / 2a
where a =3 , b=-12 and c =-1 from our equation above
{ -(-12)+- sqrt[ (-12)^2 - 4(3)(-1) ] } / [2(3)]
{ 12 +- sqrt [ 144 + 12 ] } / 6
{ 12 +- sqrt (156) } / 6
2 +- {sqrt ( 4 *13) } / 6
2 +- { 2 sqrt (13) } /6
2 +- sqrt (13) /3
there you go :)
