Answer:
30 units²
Step-by-step explanation:
Area of a parallelogram = Base * Height
Substitute in known values
Area = 6 * 5
Area = 30 units²
Hope this helps :)
Equations can have one solution, but inequalities have infinite solutions.
Hope this helps!
Answer:
i need help with something like that aswell
Step-by-step explanation:
It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30
We know that Step 1 is correct, because it is just a restatement of the equation. Therefore, we can eliminate Step 1:
2(5y – 2) = 12 + 6y
In Step 2, the student tried using the Distributive Property. The Distributive Property can be written as one of the two following formulas:
a(b + c) = ab + ac
a(b – c) = ab – ac
In this case, we'll use the second formula. Substitute any known values into the equation above and simplify:
2(5y – 2) = 2(5y) – 2(2)
2(5y – 2) = 10y – 4
In Step 2, the student calculated 2(5y – 2) to equal 7y – 4. However, we have just proven that 2(5y – 2) is equal to 10y – 4.
The student first made an error in Step 2, and the correct step is:
Step 2: 10y – 4 = 12 + 6y
I hope this helps!
