Step-by-step explanation:
Given:
The expression is
To find:
The value of given expression when x=5.
Solution:
We have,
Substituting x=5 in the above expression, we get
On further simplification, we get
Therefore, values of the given expression at x=5 is 87.
Answer:
Length: 9
Width: 2
Step-by-step explanation:
Area = length × width
18 = (x - 5)(x + 2)
18 = x² - 5x + 2x - 10
x² - 3x - 28 = 0
x² - 7x + 4x - 28 = 0
x(x - 7) + 4(x - 7) = 0
(x - 7)(x + 4) = 0
x = 7, -4(not possible)
Length: 7+2 = 9
Width: 7-5 = 2
