Answer:
82
Step-by-step explanation:
because 63% of 130 is 81.9
and since the question is asking approximately which means rounding, so you round 81.9 to get 82.
Answer:
This is true.
Step-by-step explanation:
Step 1: see that √27 is the same as √3*3*3 and thus 3√3
Step 2: remove parenthesis so that 2(1-3√3) becomes 2 - 6√3
Step 3: observe that the equation now becomes 6√3 + 2 - 6√3 = 2
if you simplify any further, you are left with 0=0, which is true.
