Answer:
Step-by-step explanation:
Let's do like-terms first which on the right side has the 2p:
17-2p=4p+5
Then make the variables on one side:
17=4p+2p+5
17=6p+5
Let's put that 5 on the other side:
17-5=6p
12=6p
Lastly, divide 6 to get a final remaining p.
12/6=p
2=p
Hope you understand :)

Answer:
7 in
Step-by-step explanation:
For width w in inches, the length is given as 2w+1. The area is the product of length and width, so we have ...
A = LW
105 = (2w +1)w
2w^2 +w -105 = 0
To factor this, we're looking for factors of -210 that have a difference of 1.
-210 = -1(210) = -2(105) = -3(70) = -5(42) = -6(35) = -7(30) = -10(21) = -14(15)
So, the factorization is ...
(2w +15)(w -7) = 0
Solutions are values of w that make the factors zero:
w = -15/2, +7 . . . . . negative dimensions are irrelevant
The width of the rectangle is 7 inches.
If AB is 128 centimeters long what is xe
