Answer:
The two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Step-by-step explanation:
Here, the length of the rectangle = (x-2) units
The width of the rectangle = 5 units
Now, AREA OF A RECTANGLE = LENGTH x WIDTH
So, here AREA = 5 ( x- 2)
= (5 x - 10) sq. units
( as by Distributive property: A (B-C) = AB - AC)
Hence, the two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
The correct Option is (A) True
Explanation: Given polynomial:
x^2 + 5x + 6
To find the factors do following steps:
Step 1:
x^2 + 2x + 3x + 6
Step 2:
x(x + 2) + 3(x+2)
Step 3: Take the common out!
(x+2) (x+3) (True)

Answer:
17 inches
Step-by-step explanation:
An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.
Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.
Now we know that for an obtuse triangle,
c > 16.64
Therefore the smallest possible whole number is 17 inches.
