Answer: 85 pages
cross multiply 60 x 17 = 1020 / 12 = 85
17 85
— = —
12 60
(9+w)w=252 or w(w+9)=252.
The quadratic equation applies: w²+9w-252=0=(w+21)(w-12), so w=12, because a negative zero is meaningless.
So the dimensions are width=12 in and length=21 in.
Ok, so amy is 8 years older than twice alica's age
if amy=y and alica=x
y=8+2x
and sum is less than 32
y+x<32
we can subsitute 8+2x for y in other equation
8+2x+x<32
8+3x<32
minus 8 both sides
3x<24
divide both sides by 3
x<8
the inequality is x<8
A. 6
The circumference can be found just by multiplying the diameter by pi.
So all you need to do is 18.84/3.14 which is 6.
It represent 13,9
Hope this helps
