what- the area of a rectangle is 45 square feet. The length is 4 feet longer than the width.Which equation could you use to find the length of the rectangle in feet?
2_x_ + 2(x – 4) = 45
What is longer length or width?
The longer side is usually called "length".
Does the length of a pendulum effect how it swings?
Yes, the length of a pendulum affects its swing. The oscillation will be longer with a longer length and shorter with a shorter length.
If the length of a rectangle is 3 feet longer than it is wide then what would the equation be for the problem?
if you are trying to find the area then: width=x length=y y=3+x xy=area 3+x*x=area
The area of a rectangle is 45 square feet. The length is 4 feet longer than the width. Which equation could you use to find the length of the rectangle in feet?
Let the length be x+4 and the width be x:- Form a quadratic equation: (x+4)*x = 45 => x^2 +4x -45 = 0 Solving the equation: x has a positive value of 5 Therefore length is 5+4 = 9 feet and width = 5 feet Check: 9 times 5 = 45 square feet

What type of light has a longer wave length ultra violent or infrared?
Ultraviolet has the longer wave length Infrared has the lower wave length
What is the longest mathematical equation?
There really isn't one..you can make any equation longer.
If the length of a rectangle is 9m longer than its width the area of the rectangle is 36m sq units find the dimensions of the rectangle?
To solve this problem, you first need to define some variables and then set up an equation. Let w = width of the rectangle and l = length of the rectangle. Since the length is 9 m longer than the width, we can write the following: w = width w + 9 = length Since the area of a rectangle is found by multiplying length x width, we can write the following equation: w(w + 9) = 36 Next, we must solve this equation. By the distributive property, we have w^2 + 9w = 36. Subtracting 36 from both sides, we get w^2 + 9w - 36 = 0 We can factor this trinomial into (w + 12)(w - 3) = 0 By the zero product property, we have w + 12 = 0 or w - 3 = 0 Solving these two equations, we have that w = -12 or w = 3. Since the width of a rectangle cannot be negative, we ignore the w = -12 solution and we find that w = 3. Since our width is 3 m, our length must be 12 m. We can check our answer by verifying that 12 m x 3m = 36 m^2.
How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
What is the longer side the length or the width?
Conventionally, length is the bigger of the two.
Is copper sulphate a reactant or a product in the following equation copper sulphate plus sodium hydroxide equals copper hydroxide plus sodium sulphate?
Copper sulfate is a reactant in the equation as stated, because it is present before the reaction has occurred and no longer present afterward.
When put together two sticks are 142cm long one stick is 22cm longer than the other how long are the sticks i need someone to set this up as a equation?
Let the length of the short stick be s cm; then: The longer stick is s + 22 cm. And the two sticks together is: s cm + (s + 22) cm = 142 cm → 2s + 22 cm = 142 cm This can then be solved for s, the length of the shorter stick; from which the longer stick length can be found.
