Answer:
Length = 10.435 inches
Step-by-step explanation:
Let the length be l
Let the width be w
Since the length is 9 inches more than half the width.
Then;
L = 0.5w + 9
Perimeter of a rectangle is;
P = 2Lw
Thus;
P = 2w(0.5w + 9)
Since perimeter = 60
Then;
2w(0.5w + 9) = 60
w² + 18w = 60
w² + 18w - 60 = 0
From quadratic formula;
w ≈ 2.87 in
L = 0.5(2.87) + 9
L = 10.435 in
X-9^2
a number = x
decreased= subtracting
square of 9= 9^2

It would be b.
Step-by-step explanation:
403x581=234143 rounded to 240,000
Hope it helped brainiest plz
We bring ecuation to the same denominator
16y -18=7y
16y-7y=18
9y=18
y=18/9=2
