For this we will use equation:
H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:
Hw = 200 + 0.5*w
To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.
The area model you can use is D , cs 70 +3 & 30+9
Answer:
(x-4)(x+11)
Step-by-step explanation:
(x-4)(x+11)
x^2-4x+11x-44
x^2+7x-44
Ding Dong!
Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
