Solve 2x+4 so that it has one solution

-2

Step-by-step explanation:

We can set it equal to zero

2x+4 = 0

2x =-4

x = -2

x = -2

Step-by-step explanation:

To solve for variables, we need the equation to be set equal to something. If no other number is given, assume zero.

2x + 4 = 0

Move 4 to the right by subtracting it from the left and right (since it is being added).

2x = -4

Next, isolate x by dividing both sides by 2 (since x is being multiplied by 2)

x = -2

We can check that this is correct by plugging in -2 for x and seeing if we get zero.

2(-2) + 4 = 0

-4 + 4 = 0

0 = 0

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
