Length is 9meters and width is 3 meters

steps:
let's assume width of a rectangle = a meters
than length of the rectangle = 3*a= 3a
perimeter = 24 meters
formula to find perimeter: p = 2(l+w)
substitute the values of in the formula
24 = 2 (3a+a)
24 = 2(4a)
24 = 8a
24/8= a
3= a
a is width of the rectangle = 3 meters
length of the rectangle = 3* a = 3*3= 9 meters
hence and is length 9 meters and width 3 meters

Write x²-10x+32 in vertex form
vichka [17]

Answer:

y = (x-5)²+7

Step-by-step explanation:

i graphed x²-10x+32 and found the vertex is at (5,7)

i used the y-intercept as a point on the curve in the formula:

y = a(x-h)²+k

32 = a(0-5)²+7

subtract 7 from each side to get:

25 = 5²a

25 = 25a

a = 1

y = (h-5)² + 7
