You can distribute the q to both terms to get
![q(2a+1) = q\cdot 2a + q\cdot 1 = 2aq+q](https://tex.z-dn.net/?f=%20q%282a%2B1%29%20%3D%20q%5Ccdot%202a%20%2B%20q%5Ccdot%201%20%3D%202aq%2Bq%20)
The formula is
A=p (1+r)^t
A future value?
P current value 140
R rate of inflation 0.034
T time 2008-2005=3 years
A=140×(1+0.034)^(3)
A=154.77 round your answer to get
A=155
Well, you can’t add them because 15 has a m and 35 doesn’t have a variable sooo? What are the answer choices?
First Method:
Round
to the closest integer, which is 1.
Round
to the closest integer, which is also 1.
So 1 + 1 = 2.
Answer for method 1: 2
Second Method:
+
= ![\frac{3*4}{5*4} + \frac{3*5}{4*5} = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%2A4%7D%7B5%2A4%7D%20%2B%20%5Cfrac%7B3%2A5%7D%7B4%2A5%7D%20%20%3D%20%5Cfrac%7B12%7D%7B20%7D%2B%5Cfrac%7B15%7D%7B20%7D%3D%5Cfrac%7B27%7D%7B20%7D)
is around 1
Answer for method 2: 1
The closest answer is 1.
A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4
