Explain how to Estimate the length of an object

Hello, I am Cordelia. I died in a fire 10 years ago. Unless you send this message on to 10 other people, I will come to your room tonight and stare at you. I look like a three-year old – without a face. I will show up every night. You have seven minutes to send this.

Step-by-step explanation:

From checmistry, we learned to measure it with a ruler, but to estimate the last digits, you have to round to the nearest whole number

Step-by-step explanation:

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
