Answer:
area is 21
Step-by-step explanation:
the formula to find the area of a triangle is
area = 1/2 x base x height
so we can plug the numbers of your triangle in to that formula
the base is 7 and height is 6
area = 1/2 x 7 x 6
area = 1/2 x 42
area = 21
Answer:
10 problems
Step-by-step explanation:
4/1 = 8/x
solve for x
x = 8/4 = 2
2 is the number of problems she still has to do
now add that to 8 to get total number of problems
Answer:
Step-by-step explanation:
This is an arithmetic sequence with first term -46 and common difference 1.
So,
Answer:
The last equation x2 - 2x -4 = 0
has solution (x - 1)^2 - 5 = 0, x = 1 + root(5) or x = 1 - root(5)
Step-by-step explanation:
If a quadratic function has roots 1 and 5
f(x) = (x -1)(x- 5)
f(x) = x^2 - 6x + 5
Unless you meant. -4 and 6 ?
g(x) = (x + 4)(x - 6)
g(x) = x^2 -2x -24
-------------------------
Or did you mean x = 1 and x =4 ?...
x^2 + 2x + 4 = 0 : complete square x^2 + 2x + 1 + 3 = 0, (x+1)^2 + 3 = 0
x^2 - 2x + 4 = 0 : complete square: (x -1)^2 + 3 = 0
0x^2 + 2x - 4 = 0, 2x - 4 = 0, x = 2
x^2 - 2x - 4 = 0 becomes: x^2 - 2x + 1 - 1 -4 = 0 ; (x - 1)^2 - 5 = 0

5. "Being settled meant being tied to land and possessions; being nomadic meant having a mobile community with a mobile food supply. This allowed nomads to attack and plunder resources. They could gain access to agricultural products without having to farm or trade."
