Perimeter of rectangle = 2(l+w)
So, 54cm = 2(l+9cm)
=> 54cm = 2l + 18cm
=> 54cm - 18cm = 2l
=> 36cm = 2l
=> 36cm/2 = l
=> 18cm = l
<h3>Answer: A) 2</h3>
=====================================================
Work Shown:
u(50654) = 5+0+6+5+4 = 20
u(20) = 2+0 = 2
u(50654) = 2
We want to find all possible values of m such that u(m) = 2 and also m is some two-digit integer.
-----
Possible values of m are: m = 11, m = 20
u(m) = u(11) = 1+1 = 2
u(m) = u(20) = 2+0 = 2
and that's it. There are no other ways to have two positive integers add up to 2.
Answer:
y = -2x-7/9
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope and b is the y intercept. Start by solving for y.
-18x-9y=7
-9y=18x+7 (divide through by -9)
y=-2x-7/9
