Area = Length x width.
30 = w x 3w +1
Simplify:
3w^2 + w = 30
Subtract 30 from both sides:
3w^2 + w -30 =0
Factor
(w-3)(3w+10) = 0
Solve for the w's:
w = 3 and x = -3 1/3
Since the number cant be negative w = 3
The width = 3 cm.
Answer:
Inverse property
Step-by-step explanation:
The definition of the inverse property is to add to get a result of zero. Since we are adding the inverse of each term to get a result of zero each time, we are using the inverse property.
Step-by-step explanation:
-3-24x-36>-111
-39-24x>-111
-24x>-111+39
-24x>-72 /x(-1)
24x<72
x<2.66
For the table, y = 9x.
so the price of a short cake is $9
For the graph, y = 4x
so the price of a sweet bread is $4
9-4 = 5
the short cake is $5 more than the sweet bread
