BE = 6cm
BD = 12 cm
For a square, the diagonal are equal
so :::
AC = BD = 12 cm
Done :)
first, lets distribute the equation. 5(n^2+n)-3n(2n^2+4n-2) would become
5n^2 +5n -6n^3 -12n^2 +6n
Now we add the like terms.
-6n^3 - 7n^2 +11n
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.
Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet
Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet
Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet
Answer:
Option A.
Step-by-step explanation:
It is given that, sales (in hundreds) for several months can be modeled by the function:
We need to find the month in which 400 toys were sold.
Substitute S(m)=4 in the given function.
Now,
or
or
or
Approx the value to the next whole number.
or
It means, 400 toys were sold on 7th and 10th month.
Therefore, the correct option is A.
The answer is 0.5
2.5/5=0.5
