The poster is a rectangle.
P = 2 L + 2 W
where L is the length and W is the width of a rectangle.
L = W + 2 1/2 = W + 2.5
103 = 2 ( W + 2.5 ) + 2 W
103 = 2 W + 5 + 2 W
103 = 4 W + 5
4 W = 103 - 5
4 W = 98
W = 98 : 4
W = 24.5 in
L = 24.5 + 2.5
L = 27 in
Answer:
The poster is 27 inches long and 24.5 inches wide.
Hey there,
Angle LKM is = 180 - 65 - 90
= 25 degrees
Hope this helps ^_^

Answer:
(a - 6)²
(3c + 1)²
30e(e - 1)²
Step-by-step explanation:
a^2-12a+36
a² - 6a - 6a + 36
a(a - 6) - 6(a - 6)
(a - 6)(a - 6)
(a - 6)²
9c^2 + 6c + 1
9c² + 3c + 3c + 1
3c(3c + 1) + 1(3c + 1)
(3c + 1)(3c + 1)
(3c + 1)²
30e^3 - 60e^2 + 30e
30e(e² - 2e + 1)
30e(e² - e - e + 1)
30e[e(e - 1) - (e - 1)]
30e(e - 1)(e - 1)
30e(e - 1)²
Y=-2/3x+300
the y intercept is 300 and the slope is -2/3
y=mx+b
