Answer:
The given expression simplified is <em>48x + 64.</em>
Step-by-step explanation:
Solving this problem entails of simplifying the expression provided. We'll use the distributive law, or the distributive property, to write the expression in the simplest form.
Distributive law states:
- a(b + c) ⟶ (a × b) + (a × c)
We know that...
Following the rules of distributive law, we can set up the expression to match this property.
a(b + c) ⟶ 4(12x + 16) ⟶ (4 × 12x) + (4 × 16)
The expression will now be easier to simplify. Here, the last step would be to multiply the terms within the parentheses. Remember that we <u>cannot</u> multiply a number by a variable. When you multiply '4' by '12x', just multiply twelve and four, and leave the variable as is.
(4 × 12x) + (4 × 16)
48x + (4 × 16)
48x + 64
Think back on what I mentioned earlier about not being able to multiply a number by a variable. The same rule applies to adding two terms, in which one is a constant and the other consists of a coefficient <u>and variable</u>. Our simplified expression has '48x', which is a coefficient and variable, and '64', which is a constant. This means we cannot add these two terms together.
Our expression seems to be in the simplest form because no further actions can be taken. The correct answer should be <em>48x + 64.</em>
Answer:
6
Step-by-step explanation:
The denominator cannot be zero, so x cannot be 6.

C. 85%
Set up the proportions
136/160 = ?/100
Then cross multiply.
100 x 136 = 13600
13600/160 = 85
Also you could use process of elimination. 296% wouldn’t work because that’s saying 136 is almost 3 times as many as 160. The other answers wouldn’t work because it’s clear that 136 is more than half of 160.
The answer to this is (6,-2)
