Answer:
90x^2+134x+48
Step-by-step explanation:
To get the area of a classroom you just multiply the length times the width
Answer: 14
----------------------------------------------
Explanation:
Using the intersecting chord theorem, we can say,
AP*PB = CP*PD
(x+2)*6 = 7*x
6x+12 = 7x
6x+12-6x = 7x-6x
12 = x
x = 12
If x = 12, then,
AP = x+2
AP = 12+2
AP = 14
Answer:
Length of route that passes the mall= 11 miles
Length of route that passes the theater= 13 miles
Step-by-step explanation:
route to school that passes the mall (highlighted in red)
= (x +1) +(x +2)
= 2x +3
route to school that passes the theater (in yellow)
= (2x +1) +x
= 3x +1
Since the first is 2 miles shorter,
2x +3= 3x +1 -2
Simplify:
2x +3= 3x -1
Bring constants to 1 side, x terms to the other:
3x -2x= 3 +1
x= 4
Substitute x=4 to find the length of each route:
Length of the route that passes the mall
= 2x +3
= 2(4) +3
= 8 +3
= 11 miles
Length of route that passes the theater
= 3x +1
= 3(4) +1
= 12 +1
= 13 miles
Alternatively, length of route that passes the theater
= 11 +2= 13 miles since it is 2 miles longer than that which passes the mall.
Option A and Option F
The expressions that represent the perimeter of rectangle are 4s + 1 and 
<em><u>Solution:</u></em>
From figure,
Length = s
Width = 
<em><u>The perimeter of rectangle is given as:</u></em>
perimeter = 2(length + width)
Substituting the values we get,

Thus option F is correct
On further simplification,

Thus Option A is correct
