Answer:
D) 27
Step-by-step explanation:
It's a rectangle so the opposite sides are congruent to each other.
<em />
<em>Long Side:</em>
6x + 6 = 42
subtract 6 from both sides:
6x = 36
divide both sides by 6:
x = 6
<em />
<em>Short Side:</em>
5y + 5 = 30
subtract 5 from both sides:
5y = 25
divide both sides by 5:
y = 5
<em />
<em>The Equation:</em>
2x + 3y
substitute in the values:
2(6) + 3(5)
do the multiplication:
12 + 15
add the values together:
27

Percent increase is a percent change that describes an increase in quantity
To determine percent increase we first find the amount of change
It is given:A tree grew from 4ft to 12ft in 3 years .
Amount of change =12-4=8 ft.
We use proportion to find percent increase.
Or ,
Cross multiplying we have:
4 ( percent Increase )= 800
Dividing by 4 we have Percent change = 200
Percent Increase = 200%.
Answer:
(0, 9)
Step-by-step explanation:
The y-intercept is the point when x = 0. By looking at the graph, when x = 0, y = 9. Therefore, the y-intercept of the line is (0, 9).
