The second term would be -3f^3 because when in descending order it is
6f^4 - 3f^3 - 2f^2 + 9f
Answer:
16 Miles
Step-by-step explanation:
For every week you simply multiply the number of miles from the previous week by 2, therefore
Week 1: 1
Week 2: 2
Week 3: 4
Week 4: 8
Week 5: 16
Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3). 
To make this expression a perfect square,
a² = 
= 
Therefore, the missing number will be 
.
Answer:
3x-4/14=9/10
You change the subtraction to addition
3x+4/14=9/10
Then you change the fractions to decimals
Step-by-step explanation:
Well,
If the length of the legs of the second triangle are proportional to the lengths of the legs of the first triangle, we could simply multiply both of the dimensions by whole numbers and get an infinite number of proportional lengths.
Example:
4.5 * 2 = 9
1.5 * 2 = 3
A triangle with legs measuring 9 meters and 3 meters will be proportional to the first triangle with leg lengths of 4.5 and 1.5 meters, respectively.
More proportional lengths:
4.5 * 3 = 13.5
1.5 * 3 = 4.5
4.5 * 4 = 18
1.5 * 4 = 6
