Answer:
Yes, -13 is less than f/2.
Step-by-step explanation:
Since we are given a fraction with a variable, it may seem hard at first to find out which number is greater.
First, we have to realise that -13 is a negative number. Any negative number is always equal to less than a positive number.
Whatever number we replace our variable f with, whether it be 2, 3, 9, or 0.00000000000001, we can rest assure that it will be a <em>positive</em> number.
Since positive numbers are greater than negative ones, -13 has to be less than f/2.
If the fraction was negative (- f/2), this would be a nearly impossible question to answer.
Answer:
Step-by-step explanation:
Prime factorize 121 and 99
121 = 11 * 11
99 = 11 * 3 * 3
Common factor = 11
Answer:
Factoring: y2-900
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 900 is the square of 30
Check : y2 is the square of y1
Factorization is : (y + 30) • (y - 30)
So for H I want to say the second one because it is spread out.
The first one is 3 . To find each of the others, multiply the previous one by 3 .
