Answer:
x=0
Step-by-step explanation:
4x+12=12
-12 -12
<u>4x=0</u>
4 4
x=0
Answer: 42
Step-by-step explanation
Switch x out with 3
using Pemdas do the exponent first
3^2 is 9
then multiply
5*9= 45
then subtract
45-3=42
The length of BD is √182
<h3>How to solve for x?</h3>
The given parameters are:
AD = 7
DC = 26
BD = x
The side lengths are represented by the following ratio:
7 : x = x : 26
Express as fraction
7/x = x/26
Cross multiply
x^2 = 182
Take the square roots
x = √182
Hence, the length of BD is √182

The number of credit hours a student have to take for the two tuition costs to be equal is 2.5 hours. Option A
<h3>Equation</h3>
c(h) = 250 + 200h
s(h) = 300 + 180h
Where,
- number of credit hours taken = h
To have equal tuition in both schools,
equate both function
250 + 200h = 300 + 180h
200h - 180h = 300 - 250
20h = 50
h = 50/20
h = 2.5 hours.
The number of credit hours a student have to take for the two tuition costs to be equal is 2.5 hours.
