Answer:
3
Step-by-step explanation:
6x - 2w + 9 - 8 = 6x - 2w +1
= 6*2 - 2*5 + 1
= 12 - 10 +1
= 2 + 1 =3

Step-by-step explanation:
The formula for the area of a rectangle is length times width
200 * 65 = 13,000
Answer:
- after 5 years, rich : poor = 11.0 : 6.7
- after 10 years, 12.2 : 9.0
- 35.3 years
Step-by-step explanation:
It is convenient to let a graphing calculator show the answers to these questions.
The exponential equation modelling the growth will be of the form ...
f(x) = (initial value) × (1 +growth rate)^x
Richland's GDP/person can be modeled by r(x) = 10·1.01^x
Poorland's GCP/person can be modeled by p(x) = 5·1.03^x
The attached graph shows values for x=5, 10 and r(x)=p(x).
It will take about 35.3 years for Poorland to catch up.
the square root property is the correct option
