Answer:
Length = 34
Step-by-step explanation:
Perimeter of rectangle = a+a+b+b = 2(a+b)
Let a = length = 2b - 4
Let b = width
Therefore
(2b-4) + (2b-4) + b + b = 106 cm
Bracket off
2b-4+2b-4+b+b = 106cm
Collect like terms
2b+2b+b+b-4-4 = 106cm
6b-8 = 106
6b = 106+8
6b = 114
b = 114÷6
b = 19
To get a
2b - 4
2(19) - 4
38-4
= 34
Answer:
14
Step-by-step explanation:

Check
14*4=56
Well this is simple all you have to do is subtract 6 dollars from 35 lets do that first
35 - 6 = 29
so she has 29 dollars to spend on each friend and she only has two....
so lets divide 29 and 2
29/2 = 14.5
so she can spend $14.50 on each of her friends:)

Answer:
origin of the graph (0)
Step-by-step explanation:
because it does not have a b value it is zero if there is no plus or minus a number at the end it is always 0 when dealing with the y=mx+b equation
Answer:
Step-by-step explanation:
ok just try to figure out the square root if their no certain number you can do an estimate.
For example 625 squared root is 125
For higher one you can use prime factorization to get the prime factors and with that you have to make groups of numbers with the number left side
