Answer:
(9.5k + 12.7m -0.4n) cm
Step-by-step explanation:
(5.9k+9.3m) + (3.6k−3.9n) + (3.5n+3.4m) = 9.5k + 12.7m -0.4n
Answer:
-1
Step-by-step explanation:
Since the denominators are the same, then we add the numerators
-6+-5/11
-11/11
-1
Answer:
y= x^2-14x+36
The equation is already in the standard form.
Answer:
B: 112.5
Step-by-step explanation:
first, we split up the rhombus into two triangles, with the height of 15 and the length of 7.5. when you multiply these you will get 112.5, and normally if you are just getting the area of the triangle, then you would divide it by two, but seeing that we have 2 triangles here, we would multiply it by two afterwards so an easier way to do it is just to not divide.
Answer:
The area of the trapezoid is 56.25² feet.
Step-by-step explanation:
The formula for the area of a trapezoid is 
- A = area (of the trapezoid)
- b = base of the trapezoid
- B = (other) base of the trapezoid
- h = height of the trapezoid
*Note: Trapezoids have 2 bases that are parallel to one another, but are not always the same length.
Using the information given to us, we can simply plug in numbers into the equation. By doing so, we'd get 
. By plugging this into a calculator, you'd get 
.
