Answer:
Length = 5 feet
Width = 4 feet
Step-by-step explanation:
Perimeter of the sandbox = 18 feet
Perimeter of a rectangle = 2(length + width)
the length of the sandbox is one foot longer than the width
Let
Width = x
length = x + 1
Perimeter of a rectangle = 2(length + width)
18 = 2{(x+1) + x}
18 = 2{x + 1 + x)
18 = 2(2x + 1)
18 = 4x + 2
4x = 18 - 2
4x = 16
Divide both sides by 4
x = 16/4
= 4
Width = x = 4 feet
length = x + 1
= 4 + 1
= 5 feet
You have to do 200 divided by 20 your answer is ten
A polynomial is a perfect square trinomial if in form
a^2x^2-2ab+b^2
look at each
we can eliminate A and B since we have -b^2 not +b^2
look at the rest
C. 5^2b-3*5*b+3^2
nope
D. 4^2x^2-2*4*3x+3^3
yes
answe is D (factors to (4x-9)^2)

Answer:
5/10 or 1/2
Step-by-step explanation:
Slope is change in y over change in x. In this case every time y goes up by 5 x goes up by 10 making the slope 5/10 and if it is simplified 1/2
