Answer:
undefined
Step-by-step explanation:
First isolate x.
12 + 4x = 6x + 10 - 2x
12 + 4x = 4x + 10
-4x -4x
12 10

Step-by-step explanation:
From the frequency distribution table given
Total Number of voters = 6.4 + 10.4 + 20.2 + 24.3 + 51.1 + 26.1 = 138.5 Million
Number of Voters 65 or Older = 26.1 million
Answer:
2a + 8
Step-by-step explanation:
9a - 7a + 4 - 4 + 8
=> 2a + 12 - 4
=> 2a + 8
Answer:
12 miles by 8 miles
Step-by-step explanation:
Let length be represented by x
Since width is 4 miles less than the length, therefore, the width will be (x-4) miles
Area=Length*Width
Area=x(x-4)=
Area is given hence
To write the above equation as a quadratic equation
By factorization, we find two numbers whose sum is -4 and product is -96, these are 8 and -12. Therefore, taking these two numbers back to our equation
(x+8)(x-12)=0
Therefore, x=-8 or 12
Equally, using quadratic formula of
for equation and in our case a=1, b=-4 and c=-96
x=-8 or 12
Since length can't be negative, hence x=12
The length is 12 miles
Width=12-4=8 miles
Dimensions: 12 miles by 8 miles
