Answer:
3x² + 3x - 36=
(3x+12)(x-3)
x² - 3x - 28=
(x+4)(x-7)
Step-by-step explanation:
For both equations use the method called the "Cross Method". It is useful for these type of factorisation questions called "Trinomials".

Answer:
7yz2+
Step-by-step explanation:
If we take the sequence terms apart and write the odd-numbered terms (the first, third, fifth, etc) and the even-numbered terms (the second, fourth, sixth, etc) in<span> own sequences we will get:
5 10 15
15 13 11
So, in the first sequence every term is obtained by adding five to the previous, and in the second sequence every term is obtained by subtracting 2 from the previous term. According to this logic, the next number in the series </span><span>5, 15, 10, 13, 15, 11, 20.</span>
Answer: 8 hours
<u>Step-by-step explanation:</u>
Company 1: 3.25x + 26
Company 2: 3.50x + 24
3.50x + 24 = 3.25x + 26
0.25x +24 = 26 <em>subtracted 3.25x from both sides</em>
0.25x = 2 <em>subtracted 24 from both sides</em>
x = 8 <em>divided both sides by 0.25</em>
<u>Check:</u>
Company 1: 3.25x + 26 = 3.25(8) + 26 = $52
Company 2: 3.50x + 24 = 3.50(8) + 24 = $52
