Perimeter is the addition of all 4 sides and a square as all the same sides. so every side will be the same. so if you divide 216 by 4 you get 54. you can check this by adding 54+54+54+54=216 or 54x4=216
Answer: 894
Step-by-step explanation:
Answer:
Number line graph with closed circle on 12 and shading to the right.
Explanation:
if you see Ezra needs $37 and if she has less than $12 then she will not have $37. she needs exactly $12 or more. The closed circle tells us that 12 is a answer and the shading to the right means more than 12.
Assuming the given is: 5u^7 - 21u^7
Since both algebraic terms are identical (both are using u^7), we can subtract the coefficients directly, as in: 5 - 21 = -16
Therefore, 5u^7 - 21u^7 = -16u^7
Answer:240
Step-by-step explanation: Either multiply 400 by 6/10 or .6. Either way you get 240.
