Step-by-step explanation:
Answer:
The answer could be A) or D) because the zero acts as a place holder. Its a little easier to derive it if you have a bigger decimal
Step-by-step explanation:
Answer:
Step-by-step explanation:
BC = 15 cm
3x = 15
x = 15/3 = 5
AB =4x = 4*5 = 20 cm
Pythagorean theorem,
AC² = AB² + BC²
= 20² + 15 ²
= 400 + 225
= 625
AC = √625 = 25 cm
AC = 25 cm
Answer:
An extraneous solution is a solution obtained through algebraic manipulations that is not a solution to the original equation.
Step-by-step explanation:
8.4/10
Every time you are dividing by 10 the decimal moves 1 time to the left so
8.4/10 is..
.84
