FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)
PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7
Whew, hope this helped :D
216 raised to the power 1/3 can also be written as cube root of 216.
Changing the given expression to radical form, we can write:
216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:
The cube root and cube cancel out each other, leaving the answer equal to 6.
So, the correct answer is option B
You divide all the sides for example 5•7•8•
Answer:
Van 8 and bus 27
Step-by-step explanation:
v+7b=197
12v+b=123 b=123-12v
v+7(123-12v)=197
v+861-84v=197
664=83v
v=8
8+7b=197
7b=181
b=27
