Comparing Radical Equations
Is the first step in solving Yx - 1 = 8 different from the first step of solving Vå - 1 = g? Explain
Yes, in the first equation, start by subtracting 8 from both sides to set the equation equal to zero, but in the
second equation, start by adding 1 to both sides to isolate the radical.
Yes, in the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by
adding 1 to both sides to isolate the radical.
No, to solve either equation, square both sides to eliminate all radicals.
No, to solve either equation, isolate the radical by adding 1 to both sides.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
