Answer:
Step-by-step explanation:
Given:
To find:
Simplified result of the radical
Solution:
If a value is in square root and it is not a perfect square then we can solve it by finding the answer by factoring down it to smaller factors which are perfect squares and finding the square root of the smaller values
Now
68 can be written as
68 = 2 * 2 * 17
The given is
It can be written as
=
Now
= 
.
so given become
∵√2² = 2
∵a*√b=a√b
A few that is charged per call.
It’s the constant which means that it isn’t going to change. It can’t be the total cost because there is no equal sign. It can’t be the cost per minute because the x represents the minutes, which means .1 represents the cost. Lastly it cannot be how long the call lasted because m is the minutes which is the length of the call.
Answer:31/40
Step-by-step explanation:
To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
Answer: 9x²-6x+5
Step-by-step explanation:
To find (gοf)(x), you want to plug f(x) into g(x). It is the same as g(f(x)).
g(f(x))=(3x-1)²+4 [distribute by FOIL]
g(f(x))=9x²-6x+1+4 [combine like terms]
g(f(x))=9x²-6x+5
Now, we know that (gοf)(x)=9x²-6x+5.
Look 4x^2-16 is 0 because 4x^2 is 16 so 16 -16 is 0
