Answer:
the answer is C
Step-by-step explanation:
let's be honest when in doubt just put c
A=45
A=kx/y
where k is constant
substituting the values for k
k= 20×9/6=30
when x=9, y=6
A= 30×9/6=45
Answer:
12 cm
Step-by-step explanation:
width = x
length = x + 5
perimeter = 38cm
perimeter = length + width + length + width
x + 5 + x + x + 5 + x = 38
4x + 10 = 38
4x = 28
x = 7
length = x + 5 = 7 + 5 = 12
A) 5/2x^3-9/4x^2+7/2x-3/2
