Step-by-step explanation:
That'd be the Substitution Property. Substitute -2 for x in x + 8 = 6 and arrive at the true statement 6 = 6.
It means on the 4th day, 88 boats will pass. So the 3rd answer down is correct.
The correct statement is D.
Step-by-step explanation:
Given,
For backyard
Length = 5x-2
Width = 2x+4
For house
Length = 5x-2
Width = 4x-12
For driveway
Length = x+10
Width = 4x-12
To find the correct statement.
Formula
The area of a rectangle = Length × Width
So,
The area of the house and the driveway = (5x-2)(4x-12) + (x+10)(4x-12)
= (4x-12)(5x-2+x+10)
= (4x-12)(6x+8)
=![24x^{2} +32x-72x-96](https://tex.z-dn.net/?f=24x%5E%7B2%7D%20%2B32x-72x-96)
=
So, the correct statement is D

Let distance of Sarah from school = x
Distance of sam from school = 3.5x or 13.3
=> 3.5x = 13.3
X = 13.3/ 3.5
X = 3.8
