Let's do these in steps. Remember to show your work
#1. Convert into a improper fraction.
3 x 2 x 1 over 2cm.
#2. Simplify 3 x 2 to 6.
6 + 1 over 2cm.
#3. Change 6+1 to 7.
7 over 2m.
We finally get 7 over 2, but that rounded would be 7. So B would be our answer.
Answer:
160, 160, 200, 200
Step-by-step explanation:
All you have to do is double the numbers.
Answer:
(x + 10)(2x + 5)
Step-by-step explanation:
Given
2x² + 25x + 50
Consider the factors of the product of the coefficient of the x² term and the constant term (ac) which sum to give the coefficient of the x- term (b)
ac = 2 × 50 = 100 and b = 25
The factors are + 20 and + 5
Use these factors to split the x- term
2x² + 20x + 5x + 50 ( factor the first/second and third/fourth terms )
= 2x(x + 10) + 5(x + 10) ← factor out (x + 10) from each term
= (x + 10)(2x + 5)
Answer:
You just have to put the numbers in order hopefully this helps.
