Answer:
x = 
± 
Step-by-step explanation:
Given
x² - 7x + 9 = 0 ( subtract 9 from both sides )
x² - 7x = - 9
Solve using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2( - )x + 
= - 9 +
(x - )² = 
( take the square root of both sides )
x - = ± 
= ± ( add
x = ± = 
According to this law, when unemployment goes up by 1%, GDP drops by 2%. In the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the GDP drops by 6%. Thus the effect is a drop in GDP by 6%.
The greatest common factor of 18 and 36 is 18.
So, 18 goes into 18 once, and 18 goes into 36 twice.
1/2 is the fraction in simplest form.
Answer:
A. Tennis: 6x+12
A. Basketball: 7x+36
B. Tennis: Length- 36, Width- 72
B. Basketball: Length- 50, Width: 94
Step-by-step explanation:
A. Tennis
perimeter equation: P= 2L+2W
P=2(x)+2(2x+6) simplify
P= 2x+4x+12
P=6x+12
A. Basketball
P= 2(1/2x+32)+2(3x-14) simplify
P=7x+36
B. Tennis and basketball
just plug in 36 for x for the original lengeth and width equations for each court
