You take the top box and combine it with the bottom right hand box and remove the right stick on the bottom box to continue combination.
Answer:
L = (x - 2) meters
Step-by-step explanation:
The area of the rectangle = (x² - 7x + 10) m²
The width = (x - 5) m
length = ?
Area of a rectangle = length × width
x² - 7x + 10 = L(x -5)
note L = length
divide both sides by (x-5)
(x² - 7x + 10)/(x - 5) = L
L = x² - 7x + 10 / (x -5)
Factorize x² - 7x + 10
find the numbers you can multiply to give you 10 and also add to give you -7
The numbers are -2 and -5. Therefore,
x² - 2x - 5x + 10 = 0
x(x - 2) - 5(x - 2) = 0
(x-5)(x-2) = 0
Let us go back to our division
L = x² - 7x + 10 / (x -5)
x² - 7x + 10 = (x-5)(x-2)
L = (x-5)(x-2) / (x -5)
L = (x - 2) meters
First multiply the 5.38 and 4.2 together to get 22.596. We will deal with it in a bit. For the bases of 10, we will add the exponents giving us 10 to the 7th power. So this is what we have so far:
. But that decimal number has to be between 1 and 10 and it's too high so we have to move the decimal one more place to the left. When we do that, we are adding one more power to the 10. The final answer in scientific notation is
7 7 / 1 7 x 3 21
--- = ---------- = ------------- = --------- = 21 miles per gallon
1/3 1 / 3 1 x 1 1
