<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

Assume you need x liters 10% acid, y liters 80% acid
Then 10%x + 80%y = 65%*70, and x+y = 70
I get: x = 15, y = 55
Answer:
False. A dilation is not.
