Answer:
21/4
Step-by-step explanation:
Rate of change also means slope.
Pick any two points, for example (8,167) and (12, 188)
Now use the formula y2-y1/x2 - x1 to find slope
188 - 167/ 12 - 8
21/4
The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>
Answer:
The total area is 444 ft².
Step-by-step explanation:
First you multiply 18 by 10 for one of the walls you get 180*2 since you have two walls with the same dimension. Next you do 12*7 to get 84. Last you would add 84 to 360 and get 444 ft²

Answer:
x = 12, y = 16
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
18(2x + 6) = 540 ( divide both sides by 18 )
2x + 6 = 30 ( subtract 6 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
-------------------------------------------
and
=
, substitute values
=
( cross- multiply )
27y = 432 ( divide both sides by 27 )
y = 16
