Evaluate the expression 2x - 5 when x =3?
A) -4
B) 1
C) 6
D) 11

B)1

Step-by-step explanation:

When you replace x with three your equation is 2*3-5. By doing order of operations you multiply 2*3 and get 6 then subtract 5 getting 1.

The answer is B!

Step-by-step explanation:

2(3)-5

6-5

1

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
