1. Original Equation 2. Subtract 6u from both sides 3. Combining 16u-6u you get 10u 4. Subtract 4 from both sides 5. Combining -21-4=4 6. Dividing by 10 7. The total of -25/10=-2.5
He is wrong. The 10 inch cube is bigger than the 5 inch cube by 5 cm in EACH DIRECTION. So, the 10 inch cube should be twice as big in volume by a factor of 2*2*2 =8 Okay let's see. 5 cm cube volume = 5*5*5 = 125 cc 10 cm cube volume = 10 * 10 * 10 = 1,000 cc
the legnth of the longest side must be LESS THAN the sum of the measures of the other 2 sides if no longest side (becasue it has 2 longest sides or 3 equal sides), then it can form a triangle
so the longest side is 36
36 must be less than the sum of 15 and 20 36<15+20 36<35 false
therfor it cannot form a triangle try it yourself, you cannot connect them that way
