The weight of galss cube with side 5 cm is 300 grams
<em><u>Solution:</u></em>
A glass cube is of side length 5 cm
Let us first find the volume of glass cube
<em><u>The volume of cube is given as:</u></em>
Thus volume of cube is 125
Given that,
So, weight of 125 cubic centimeter of glass cube is found by multiplying weight of 1 cubic centimeter of glass cube by 125
Thus weight of galss cube with side 5 cm is 300 grams
Answer:
{- 11, - 1 }
Step-by-step explanation:
Since the coefficient of the x² term is 1 , to complete the square
add (half the coefficient of the x-term )² to both sides
x² + 2(6)x + 36 = - 11 + 36 ← complete the square on the left side
(x + 6)² = 25 ( take the square root of both sides
= ±
x + 6 = ± 5 ( subtract 6 from both sides )
x = - 6 ± 5
x = - 6 + 5 = - 1 or x = - 6 - 5 = - 11
