Could someone please help me with the steps for this problem? Factor by grouping: w²+3w+w+3

Please see steps below

Step-by-step explanation:

In order to factor by grouping, we divide the four terms given into two groups, and extract on each group any common factor  we can.

In our example, we can select the terms:  and as one of our groups, and and 3 in the other group. Then we re-organize the expression as:

Now we extract from the first binomial group, the factor as a common factor of both terms, and from the second group we extract the factor "3" as common factor of those two terms:

We notice now that after the extraction, we are left with two exactly equal binomial factors that appeared in the first group and in the second group. We proceed then to extract it as common factor for the two groups:

this last product of two binomials ( is the result of factoring the original expression.

i pretty sure it is

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
