You need algebra, aka 2x+4-5y. things like that
using the formula above for finding area of trapezoids
a= 20in.
b=29.2in.
h= height= 12.5in.
(a+b)=20+29.2=49.2in.
(a+b)h= (49.2)12.5= 49.2×12.5=615in.
1/2(a+b)h= 1/2 × 615 in.= 615/2= 307.5in.
therefore the area of the trapezoid is 307.5in.
Answer:
Family Function
Step-by-step explanation:
If you subtract the amount that Jack spent on the book ($8.72) from the amount of money that Jack originally had ($20.08) then you get $11.36 left over.
