Step-by-step explanation:
Mary needs 8 boxes to put 96 muffins in dozens so 96÷12 gives you 8
The given expression is
First, we use the distributive property to get rid of the parenthesis.
Then, we reduce like terms. -2x and 3x are like terms, also 7 and 10 are like terms.
<h2>Therefore, the simplest form of the given expression is <em>x + 17</em>.</h2>
Answer:
<h2>6</h2>
Step-by-step explanation:
3b - 7 < 32
=> 3b < 32 + 7
=> 3b < 39
=> b < 39÷ 3
=> b < 13
Hope it helps !!!
Answer:
z^2 + (-1 + 5·i)·z + 14 - 7·i = 0
(1 + 2·i)^2 + (-1 + 5·i)·(1 + 2·i) + 14 - 7·i = 0
(1 + 4·i - 4) + (-1 - 2·i + 5·i - 10) + 14 - 7·i = 0
0 = 0 --> true
z^2 + (-1 + 5·i)·z + 14 - 7·i = 0
(1 - 2·i)^2 + (-1 + 5·i)·(1 - 2·i) + 14 - 7·i = 0
(1 - 4·i - 4) + (-1 + 2·i + 5·i + 10) + 14 - 7·i = 0
20 - 4·i = 0 --> false
