Answer:
14x + x^2
------------------
9x^2
Step-by-step explanation:
2x /x^2 + (x-4)/ 9x
Cancel the common factor of x in the first term
2 /x + (x-4)/ 9x
We need a common denominator of 9x
2 /x *9/9 + (x-4)/ 9x
18/9x + (x-4)/9x
Add the numerators
18+x-4
--------------
9x
14+x
----------
9x
Multiply the top and bottom by x to get it to match one of the answers
14x + x^2
------------------
9x^2
10 pencils. if he had 4 packs of pencils and each pack contained 10 pencils he would have 40 pencils (4x10) and if he gave 3/4ths of it away he would have one 4th left, so just divide 40 by 4
Answer:
w>11, w>10, w<15, w<11.
Step-by-step explanation:
w is the weight of Diego's dog. The weight must be more than 10 (w>10) but less than 15(w<15), so the inequality must be 1010 and w<15 then the following inequalities should be true:
w>11
(The weight can be more than 11 kilograms as long as it does not go past 15 kilograms.)
w>10
(This is one of the original inequalities. Weight has to be more than 10.)
w<15
(This is also one of the original inequalities. Weight has to be less than 15.)
w<11
(The weight can be less than 11 as long as it is more than 10.)
Not true:
w>15
(The weight cannot be more than 15 as stated in the question.)
w<10
(The weight cannot be less than 10 as stated in the question.)
Answer:
solve each proportion
how do you do this?
Step-by-step explanation:
The left side can be written as a square. We can take the square root, then subtract 1.
... (x +1)² = 17
... x +1 = ±√17
... x = -1 ±√17
