Write the expression in standard form.
-3x + (2 + 4x)

x+2

Step-by-step explanation:

Add −3x and 4x

Answer and explanation:

Simplify by combining like terms:

(-3x + 4x) + 2

x + 2

So, x + 2 is the simplified version of this expression, but perhaps you meant make this an equation by adding a y to the other side, since this isn't currently a linear equation.

If the equation were:

y = -3x + (2 + 4x)

then it would be this in standard form:

y = x + 2

-x + y = 2

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
