Write an equivalent expression for 8(3+5x)+ 7x+4 if x = 3, is the solution to both expressions the same?

Step-by-step explanation:

Ok, this is a simple problem. All we have to do is plugin, go back to the original and simplify and lastly plugin

A)Lets start with part A: Plugging In

Lets replace all the x's with 3 so we get: 8*(3+5*3)+7*3+4Now lets do everything in the parenthesis so we can remove the parenthesis and we get: 8*18+7*3+4Now we can do all the multiplication and get: 144+21+4

Finally we finish part A with addition and get: 169

B)Lets put that aside and move onto part B

Simplifying 8(3+5x)+ 7x+4First distribute 8 among 3+5x and we get: 24+40x+7x+4Now we combine all like factors and get: 28+47xThats our expression that is equivalent to 8(3+5x)+ 7x+4

C)Now all we have to do is Part C which is plug 3 into 28+47x

First lets replace all the x's with 3 so we get: 28+47*3Now lets do the multiplication and that is: 28+141Finally lets finish with the addition: 169

And 169 is the same solution as the one it part A! So that means 28+47x is an equivalent expression to 8(3+5x)+ 7x+4

The method to find the female dormitory is 2-d=800

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
