To solve the expression (0.7+a) x (3+z), we can use the distributive property of multiplication. This property states that when we have a product of two terms added to another term, we can distribute the multiplication to both terms and then add the results.
So, let's apply the distributive property to our expression:
(0.7+a) x (3+z) = 0.7 x 3 + 0.7 x z + a x 3 + a x z
Now, we can simplify each term:
0.7 x 3 = 2.1
0.7 x z = 0.7z
a x 3 = 3a
a x z = az
