Answer:

Answer:

x = -2 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 5 x + 6 = 0

The left hand side factors into a product with two terms:

(x + 2) (x + 3) = 0

Split into two equations:

x + 2 = 0 or x + 3 = 0

Subtract 2 from both sides:

x = -2 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = -2 or x = -3

Answer:

x= -4/2 = -2

i believe this is it

Which best explains if quadrilateral WXYZ can be a parallelogram? WXYZ is a parallelogram because diagonal XZ is bisected. WXYZ is not necessarily a parallelogram because it is unknown if CZ = CY. WXYZ is a parallelogram because ZC + CX = ZX. WXYZ is not necessarily a parallelogram because it is unknown if WC = CY.

Answer:

Step-by-step explanation:

The answer is (D) Because it is a quadrilateral in the WXYZ Form in the given figure. Because the 4 side figure doesn't have measurements we can't be certain that it can be converted into a parallelogram. If there were measurements of

Dave can bike 6 miles in 30 minutes. How far can he bike in 45 minutes?

9 miles bc

5 mins is 1 mile

bc 5*6 is 30

5 mins is 1 mile
