<h3>Option D</h3><h3>The simplified version of 7x − 4(x − 8) = 56 is 3x + 32 = 56</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
Use distributive property to simplify the expression
By distributive property,
a(b + c) = ab + ac
Therefore,
Combine the like terms : 7x - 4x = 3x
Therefore,
Thus option D is correct

Answer:
10 years
Step-by-step explanation:
Given
Decline from (0,h) to (10,0)
See attachment for graph
Required
Determine the age when height = 0
The function of the graph is represented as: (age, height)
So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)
From the attached graph;
when
<em>Hence, the age of the car is 10 years</em>
