Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm

5−(2w−8)=6w−9
Show Steps
Expand 5−(2w−8): −2w+13
−2w+13=6w−9
Subtract 13 from both sides
−2w+13−13=6w−9−13
Simplify
−2w=6w−22
Subtract 6w from both sides
−2w−6w=6w−22−6w
Simplify
−8w=−22
Divide both sides by −8
−8w
−8 =

Answer:
x = $11400
Step-by-step explanation:
Naomi is paid $190 per week plus 5.5% of her total sales in dollars, x, which can be represented by g ( x ) = 190 + 0.055 x.
And Josiah is paid $475 per week plus 3% of his total sales in dollars, x, which can be represented by f ( x ) = 475 + 0.03 x
Let the weekly pat for them are equal.
Then, g(x) = f(x)
⇒ 190 + 0.055 x = 475 + 0.03 x
⇒ 0.025 x = 285
⇒ x = $11400
Therefore, for the value of x = $11400, that will make their weekly pay the same. (Answer)
slope = (y2 - y1)/(x2 - x1)
4/3 = (-3 - r)/(2 - 5)
4/3 = (-3 - r)/(-3)
-4 = -3 - r
-1 = -r
r = 1
