WILL MARK BRAINLIEST! The area of a rectangle is equal to its length times its width. If the area of a rectangle is 14x + 42 square feet, which option(s) could be the length and width of that rectangle? Select all that apply
2 feet long and (x + 7) feet wide

14 feet long and (x + 3) feet wide

14 feet long and (x + 5) feet wide

7 feet long and (2x + 6) feet wide

2 feet long and (7x + 20) feet wide

Second one and the fourth one.

Step-by-step explanation:

Let’s look at this. When we are finding the area of the rectangle, we multiply the length times the width. Let’s look at the first option.

2 times (x + 7)

2x + 14

this one won’t work.

second one:

14(x + 3)

14x + 42

this works.

thrid one.

14(x+5)

14x + 70

nope.

fourth one.

7(2x+6)

14x + 42

works.

fifth one,

2(7x +20)

14x + 40

dpes not work.

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
