Answer:
The solutions are y=0, -5/2
Step-by-step explanation:
-3y(2y+5)=0
We can use the zero product property
-3y =0 2y+5 =0
y =0 2y = -5
y = -5/2
The solutions are y=0, -5/2
Answer:
A.
Step-by-step explanation:
A quadrilateral is simply a shape with 4 sides, therefore it does not HAVE to be 3-D.
Answer:
x = -4, x = 1
Step-by-step explanation:
x^2 + 3x - 4 = 0
4 and -1 add to 3 and multiply to -4.
(x+4)(x-1) = 0
Separate these by the Zero Product Property.
x+4 = 0
x-1 = 0
Solve.
x = -4
x = 1
