Answer:
(You only need to give one solution)
Step-by-step explanation:
We have the following equation
First, we need to foil out the parenthesis
Now we can combine the like terms
Now, we need to factor this equation.
To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.
The pair of numbers that would do this would be 1 and -4.
This means that our factored form would be
As the first binomial is a difference of squares, it can be factored futher into
Now, we can get our solutions.
The first binomial will produce two complex (Not real) solutions.
So our solutions to this equation are
Answer:
2800m
Step-by-step explanation:
Assumption:
Start point from which Percy Cod walks is "x"
If he walks around a perimeter that is the shape of a rectangle,
Length of area = L = 1000m
Width of area = W = 400m
Distance around the rectangle = D = 2 * (L + W)
D = 2 * (400+1000)
D = 2 * 1400
D = 2800m
Answer: Can you explain more? you have to calculate it by an theorm
Step-by-step explanation:
Answer:
Step-by-step explanatio
We look for the side
To know how many meters of wire we must first know the measurement of the sides of the land. They give us a land area of 196 m², as the land is square, we can take the square root of the area and we have the dimension of the sides
L = √196 m²
L = 14 m
Once the value of the side of the land is obtained, we proceed to determine the perimeter of the land, which will give us the size of the wire to fence
P = L + L + L + L
P = 14m + 14m + 14m + 14m
P = 56 m (this is the dimension of the wire for one turn of the ground)
They ask us for 5 laps.
56m * 5 = 280m
it takes 280 m
The answer is (d) first you solve 3/4
