Step-by-step explanation:
√a = 1√a so we can solve them easily:
b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7
d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6
g) √2+2√2= 3√2
j) √5+5√5 - 3√5 = 3√5
k) 2√3 + √3 - 5√3= -2√3
I) 5√11 + 7√11 - √11 = 11√11
Answer:
The black tulle is the better buy
Step-by-step explanation:
You will need to find the unit rate for the tulle...in other words cost per 1 yard to see which is the better buy.
You also need to make sure they are in the same units. So, we will convert the 3 yards to feet....which will be 9 feet
5.63/9 = 0.62555 per foot
3.58/6 = 0.59666 per foot
C
I think this is the right answer
Answer: 14x^7
You add the coefficients (numbers to the left of the variable terms) to get 6+8 = 14 which is the coefficient of the final answer. The x^7 stays the same. It's like saying "we have 6 apples added to 8 apples, so there are 14 apples overall". Replace "apples" with "x^7" and it's the same idea.
