Answer:
18ft
Step-by-step explanation:
L = length
W = width
l = w + 2ft ; because the is 2 ft longer than width
The area of a rectangle is lw
You can take the first equation ( l = w + 2 ) and plug it in lw
like this: lw ---> (w+2)w = w^2+2w
then from the question you get: w^2+2w=19.25
you use the quadratic formula and get w = 3.5
then from the first equation, you get l = 3.5+ 2 so the length is 5.5
lastly, you use the perimeter formula: 2(l+w) so 2(9) = 18
so 18ft
-6p < 12 Divide -6 on both sides to get "p" by itself

p > -2
When you divide or multiply a negative number to both sides of the inequality, the sign (< , > , ≤ , ≥) is flipped.
Answer:
y =20
Step-by-step explanation:
you have to get the y by itself so what you do on one side you do to the other. subtract 12 on both sides and you get y=20
Divide 45 by 150 then multiply by 100:
45 / 150 = 0.3
0.3 x 100 = 30%
The answer is 30%
