Answer:
Step-by-step explanation:
x² + 11x + 24
x² + 3x + 8x +24
x ( x + 3 ) + 8 ( x + 3 )
( x + 3 ) ( x + 8 )
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
The answer is 132.
9/11
4 1/2= 9/2=11/2n
so n =9/11
so 9/2=11/2*9/11
78.4
