Answer:
Last option: Square both sides of the equation in step 1 to eliminate the square root.
Step-by-step explanation:
The error is in the process of subtracting 3 from both sides, since +3 is inside the root.
In order to be able to operate with the terms that are inside the root, we need to eliminate the root, and for that we need to square both sides of the equal sign.
Answer:
Step-by-step explanation:
so what your gonna do is you are going to add 81 to 360 and then sum it up. after you are going to divide it by 3.5.
This might be wrong but there is always a point where you have to try :)
Answer: 1372 Square meters
Step-by-step explanation:
7*14+28*14+7*14+7*28+14*28+7*28=1372
Answer:
Given the statement: if y =3x+6.
Find the minimum value of 
Let f(x) = 
Substitute the value of y ;

Distribute the terms;

The derivative value of f(x) with respect to x.

Using 
we have;

Set 
then;


By zero product property;
and 2x + 3 = 0
⇒ x=0 and x = 
then;
at x = 0
f(0) = 0
and
x = -1.5

Hence the minimum value of
is, -5.0625
