Answer:
w=10 feet
l=21feet
Step-by-step explanation:
let width be x
p=2l+2w
p=62
so we form the equation
l=1+2x
w=x
2(1+2x)+2(x)=62
2+4x+2x=62
6x=60
x=10feet
w=10feet
l=1+2x
l=21feet

Answer:
840
Step-by-step explanation:
7, 14, 42, 168, ?
7 x 2 = 14
14 x 3 = 42
42 x 4 = 168
you see the pattern?
hence,
168 x 5 = 840 (ans)
Hi There! I’m happy to help! Answer: $23.05
Step-by-step explanation:
First, since there is 3 shirts that cost $25.65, multiply them. Product is $76.95. Now, we subtract the $76.95 from the $100, making $23.05 her change. Hope this helps!
note that gradient = at x = a
calculate for each pair of functions and compare gradient
(a)
= 2x and = - 1
at x = 4 : gradient = 8 and - 1 : 8 > - 1
(b)
= 2x + 3 and = - 2
at x = 2 : gradient = 7 and - 2 and 7 > - 2
(c)
= 4x + 13 and = 2
at x = - 7 : gradient = - 15 and 2 and 2 > - 15
(d)
= 6x - 5 and = 2x - 2
at x = - 1 : gradient = - 11 and - 4 and - 4 > - 11
(e)
y = √x =
= 1/(2√x) and = 2
at x = 9 : gradient = and 2 and 2 >
