length = 3234 m and width = 1614 m
let the width = w then length = 2w + 6
Perimeter = 2 ( length + width )
= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12
given perimeter = 9696 the equating gives
6w + 12 = 9696
subtract 12 from both sides
6w = 9696 - 12 = 9684
divide both sides by 6
w = = 1614
width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
7. Factor. (x - 2)(4x + 5) = 0 The zeroes are 2 and -5/4. The answer is C.
8. Vertex form is: f (x) = a(x - h)^2<span> + k and (h, k) is the vertex.
So plug in. f(x)=a(x+1)^2-10
Plug in x and y to find k.
2 = a(1+1)^2-10
2=a(2)^2-10
2=4a-10
4a=12
a=3
f(x)=3(x+1)^2-10
H is the answer.</span>
S / 180 - 2 = n The / means over not divide
Answer:
L = 0.02d + 10
Step-by-step explanation:
The hair starts at 10 inches long.
L = 10
Now we add 0.02 inches in length per day.
In 1 day, it grows 0.02 inches.
In 2 days, it grows 0.02 * 2 inches.
In d days, it grows 0.02d inches.
Now we add the starting length, 10, and the growth per day, 0.02d, to get:
L = 0.02d + 10
