What is the vertex of the parabola whose equation is y = (x + 1)^2 + 3?
dalvyx [7]
The y-value of the vertex is positive 3, as shown by the +3 on the right hand side of the equation, and the x-value is -1, from the (x+1)^2 (remember, when the number is inside the brackets, flip the sign) The vertex would be (-1, 3) 

If you are looking for a rigorous answer (calculus), we must find the mininum point of the equation: f(x) = (x+1)^2 + 3 f
f'(x) = 2(x+1) = 2x + 2
2x + 2 = 0 
x = -1
f(1) = (-1 + 1)^2 + 3
f(1) = 0 + 3 = 3
(-1, 3)

A rectangle has a perimeter of 54 cm. It has a length of 15 cm. What is its area? *
d1i1m1o1n [39]

the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.

3. What is wrong with the following statement? If d/e = f, then d multiplied by f = e.f should be divided by e.F and e should be
Molodets [167]

the initial statement is:

\frac{d}{e}=f

and then:

d\cdot f=e

So the second statement is false because f should be multiply by e, not by d so is option C)
