Answer:
Step-by-step explanation:
Area of rectangle = Length × Width
The given rectangle has a length if x meters
The width of the triangle is (x-3) meters
The area of the rectangle is given as 10 square meters.
Area if rectangle = x(x-3) = 10
Multiplying each term in the parentheses,
x^2 -3x = 10
x^2 -3x -10 = 0
This is a quadratic equation
We will look for two numbers such that when they are multiplied, it will give us -10x^2 and when they are added, it will give -3x. It becomes
x^2 + 2x - 5x -10 = 0
x(x+2)-5(x+2) =0
( x + 2)(x-5) = 0
x = -2 or x = 5
The length of the rectangle cannot be negative so the length is 5 meters
Widith = x+3 = 5-3 = 2 meters
Okay my example will be for if you watched that tree for like 5 years and I can`t really put in a graph here so sorry about that
The equation is basically the original height, 5 foot, and multiply it by the number of years you`ve been watching it grow for example when you watch it for 6 years then it will be the original height of 5 foot multiplied by the number years it has been since you look at it which is 6 years. 5 * 6 = 30 so after 6 years it will grow 30 inches.
1st year: 5 foot
2nd year: 5 foot * 2 = 10 inch increase in height
3rd year: 5 foot * 3 = 15 inch increase in height
4th year: 5 foot * 4 = 20 inch increase in height
5th year: 5 foot * 5 = 25 inch increase in height
So basically the equation is 5 foot * the number of years its been = total increase in height
I hope this helps
The least common denominator of 36 and 48 is 2. :D
Answer:
4d
Step-by-step explanation:
i think any variable alone with no coefficient equals one
so this problem is like adding the terms 3d + 1d
so 1+3=4
and you use the variable d at the end
therefore the answer would be 4d
hope this helped<3
6 x 2 minus 20 because 6 x 2 is in parenthesis so it comes first
