Answer:
The value of RA is " 9.43".
Step-by-step explanation:
In the given question there is some typing mistake so, the points are:
R =(2, 5)
A= (-3, -3)
Find:
RA= ? where it is a distance (D).
Formula:

put the value in the formula:

Answer:
58=58
Step-by-step explanation:
44+14=28+30
58=58
Answer:
x² + 6ax + 4bx + 5a² - 5b²
Step-by-step explanation:
(x+5a+5b )(x+a-b)
x² +a x -bx +5ax + 5a² -5ab + 5bx + 5ab -5b²
x² + 6ax + 4bx + 5a² - 5b²
So first you take the words and put them into an equation. "a number" that never gets directly told to you will always be a variable, which is easiest to make X. "The sum of a number and 8" will mean that 8+something is the sum so they have to go in parenthesis... giving you
4/3*(x+8)=24
now just solve for X, remembering to use the reverse of PEMDAS, since you're solving for the variable.
remove what is furthest away to the X first.
x+8=24*3/4
x+8=18
x=18-8
x=10
Now, remember to always go through and replace your variable with its value and solve. if it is not equal on both sides, retry the problem because you may have missed a small +, -, or * somewhere!
Hope this helped:)
