Im pretty positive you multiply all the sides then you get your answer so
5.2 x 2.4
12.48
take 12.48 * amount of sides which is 12
answer 149.76
hope im right and hope that helps!
Answer:
total there are 3 values of x as +5/3, -5/3 and 0
Step-by-step explanation:
the given equation is
x(6x-10) (6x+10)=0
this equation can be solved as following
=0 using the formula (a+b)*(a-b)= (a^2-b^2)
here a=6x and b=10
from here we can write either x=0 or 36x^2= 100
or x^2= 100/36 and x=0
or x= ±10/6 and x=0
therefore, total there are 3 values of x as +5/3, -5/3 and 0
Complete Question
Jessica pays a flat rate of $70 for her cell phone and is charged $0.05 for every text she sends. Jessica wants to spend less than $80.00 per month on her cell phone. Write and solve an inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $80.00.
Answer:
<em>Inequality: </em>70 + 0.05x < 80
<em>Solution: </em>x < 200
Step-by-step explanation:
Let x represents the minimum number of SMS.
If 1 SMS is charged at $0.05, then x SMS would be charged at $0.05x
Considering that she pays a flat rate of $70.
The inequality to represent the minimum number of SMS she needs to send is:
70 + 0.05x < 80
To solve this inequality, follow the following steps
Collect like terms
0.05x < 80 - 70
0.05x < 10
Divide through by 0.05
0.05x/0.05 < 10/0.05
x < 10/0.05
x < 200
The solution to the inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $80.00 is x < 200.
Answer:
The sum of the remaining angles would be 220°.
