Step-by-step explanation:
-2+8 is the same as 8-2 which equals 6.
Answer:
20
Step-by-step explanation:
To find Hypotenuse: Pythagorean Theroem
a^2+ b^2= c^2
The legs are A and B
The side that is directly across from the Right angle is C
12^2 + 16^2 =C^2
144+256=400
400 = c^2
Square root on both sides to get rid of c^2
The square root of 400 is 20
c=20
Answer:
y=(x^2 -2x-3)/3
Step-by-step explanation:
f(x)= √3x+4 -1
x=√3y+4 -1
(x+1)^2=(√3y+4)^2
3y+4=x^2 +2x+1
3y=x^2 +2x-3
y=(x^2 +2x-3)/3
Answer:
25
Step-by-step explanation:
Changing the coefficient of x to 6 changes the meaning of the expression as 5 is added to 6 times x
Solution:
Given that number 2 in the expression 5 + 2x is called the coefficient of x
We are asked to find what happens when changing the coefficient to 6 changes the meaning of the expression
In the expression,
5 + 2x
This means 5 is added to 2 times x or 5 is added to twice of x
Number 2 is called the coefficient of x
When we change this coefficient to 6, the expression becomes,
5 + 6x
So now the meaning of expression becomes,
5 is added to 6 times x
So changing the coefficient of x changes the meaning of the expression
