Answer:

14,800in^2

Step-by-step explanation:

ok so to find the area of a trapezoid, we use the equation A=((a+b)/2)h. So Area is equal to base a (the one on the top) plus base b (the one on the bottom) divided by two (so a+b/2) and then multiply that number by h (the height. So we do it like this

(145+225)/2 x 80

But remember, we follow PEMDAS, so we multiply first

(a+b)80

370(80)= 29600

now we can divide

29600/2= 14,800sq in (or in^2)

14800

The scale for a map says that 1 cm is equal to 25 miles. Jennifer measures the distance between two cities as 4.5 cm. How far apart are the cities?

Answers

112.5 miles because 4x25=100 and half of 25 is 12.5 so 100+12.5= 112.5
technically 4.5x25=112.5

1 cm = 25 miles
therefore 4.5cm = (4.5 x 25)miles
Answer = 112.5 miles

If you were to solve a function and you are subtracting from x do you subtract or addG(2)-2=2squared-2
what do you do with the minus 2 at the beginning?

Answers

well what you do is you leave it since g(x) is a function
iff you don't know what g(x) is, then treat g(x) as an unknown, or ?

?-2=2^2-2
add 2 to both sides
?=2^2
?=4
g(2)=4
