(n+2)(n+6)
Graph for x-intercepts, or find what adds up to b and multiples to c using formula ax^2+bx+c
The length of the hypotenuse is 5.83 inches long so between 5 and 6 inches
We have that
n 12 part a)
actual distance-------------> 124 miles
map distance----------------> 4 cms
scale factor of the map =124 miles/4 cms=31 miles/cm
n 12 part b)
map distance=21 cms
actual distance?
[actual distance]=[map distance]*factor scale-----------> 21*(31)=651 miles
n 13)
we know that
(13.5/9)=(x/8)--------------> x=(13.5/9)*8-----------> x=12 units
n14)
we have that
x/26=(32-x)/18-----------> 18x=832-26x--------> x=18.91 units
She would have traveled 24 miles since from the house to the supermarket is 7 miles then from the supermarket to the municipal building is 5 miles then back 7 miles and then 5 miles. If you add all of that together then you will get 24 miles.
I would estimate 7 10/12 to 8 and i would estimate 2 11/12 to 3 so 8 plus 3 would equal 11 so that would be the estimate. the actual would be 10 8/11 so the estimate would be bigger.
