The first one is 4n+7=15, the second one is 1/4(n-15), the third one is 1/4n-15, the fourth one is n/7=4, and the last one is n4+7=15
Answer:
D. Linear, because the function increases by a common difference

Since ABC is a 90-60-30 triangle, it is half of an equilateral triangle. This means that BC is half AC, i.e. 17.
So, we have
So, the perimeter is
Answer:
(x - 7)(x + 3) = 0
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, thus
(x - 7)(x + 3) = 0 ← in factored form
Answer:
a.
b.
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width
a. We know that the kitchen measures 3.75 meters by 4.2 meters; then we can say that:
Therefore, substituting these values into the formula, we get that the area of the kitchen is:
b. The area of the living room is one and a half times (1.5 times) that of the kitchen, this is:
Therefore, the total of the living room and the kitchen is:
