Answer:
x=13.7
Step-by-step explanation:
CD=CB=6
AC=AD+CD => AC=9+6 => AC=15
AC^2= AB^2 + BC^2 => 15^2 = X^2 + 6^2 => 225 = X^2 + 36 => X^2 = 225 - 36 => X^2 = 189 => X=13.7
A is the only correct answer, unless you meant to put “-5” for letter E. Then A and E would be the correct answers!
Answer:
the difference between the given matrices is option 2nd
Answer: x=2/3
Step-by-step explanation:
|2x - 3|= 4x - 1
2x-3=4x-1
2x=4x+2
-2x=2
x=-1
4(-1)-1=
-4-1=-5 ==> Absolutes values can't equal a negative number
-(2x-3)=4x-1
-2x+3=4x-1
3=6x-1
6x=4
x=4/6
x=2/3
5*6=20+y
30=20+y
30-20=20-20+y
10=y
Check answer by using substitution method
5*6=20+y
30=20+10
30=30
Answer is y=10
