Hi so remember the perimeter of a square is 4 times the side. so if the perimeter is 36 then you can divide 36 by 4 to get the answer 9.
36=4^x
36=4x
36/4=x
9=x
to cross check if ever unsure times the (side) by 4 if it matches the given perimeter.
6-(-5)
6+5 = 11
The answer is D!
If the plant grows 0.4 cm per week....in 3 weeks, it will have grown :
3 * 0.4 = 1.2 cm
Answer:
x = 2
Step-by-step explanation:
Given a line parallel to a side of a triangle and intersecting the other 2 sides then it divides those sides proportionally, that is
=
( cross- multiply )
6x = 4(x + 1)
6x = 4x + 4 ( subtract 4x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
F(2)=4+10-8=6; f(6)=36+30-8=58. Average rate of change is (58-6)/(6-2)=52/4=13
