Answer:
width: 4cm
length: 13cm
Step-by-step explanation:
Let the width of the rectangle be w. From the problem, we can infer that the length would be equal to 3w + 1. The formula for the perimeter of a rectangle is:
P = 2(l + w)
where P is the perimeter, l is the length, and w is the width.
We can substitute our values into the equation:
34 = 2(3w + 1 + w)
17 = 3w + 1 + w
17 = 4w + 1
16 = 4w
w = 4
We can substitute this into the length:
3w + 1
3(4) + 1
12 + 1
13
The prime factorization of prime number "a" is just "a"
The prime factorization of prime number "b" is just "b"
The lowest common multiple of the two prime numbers will just be the product of the two: a*b.
So Richie is right.

Answer:</h3>
y +3 = (1/4)(x +3)
<h3>
Step-by-step explanation:</h3>
The two-point form of the equation for a line is good for this.
... y -y1 = (y2-y1)/(x2-x1)(x -x1)
Substituting your values, we have ...
... y -(-3) = (-1-(-3))/(5-(-3))(x -(-3))
... y +3 = 2/8(x +3)
Since you ask for "an equation," we can leave it in this form.
... y +3 = (1/4)(x +3)
_____
Or we can rearrange it to <em>slope-intercept form</em>:
... y = (1/4)x -(2 1/4)
or put it in <em>standard form</em>:
... x -4y = 9
1. 79% Take 100 x 21%=21, then subtract 21 from 100 = 79
2. $138 Take 1200 x 11.5%= $138
Use Slide method for some of them, some are perfect squares:
