Group like terms, in this case terms with variables and terms without. (m + 11) + (n + 44) = (m + n) + (11 + 44) Then simplify. (m + n) + (11 + 44) = (m + n) + 55 = m + n + 55 Final answer: m + n + 55
Dave is incorrect in his assertion that a rectangle is merely a quadrilateral with two lines of symmetry. The thing is said to be in symmetry when an imaginary line splits it into two equal halves. The rectangle is not the only figure with two lines of symmetry; the square and rhombus are also forms with two lines of symmetry. As a result, Dave's assertion is incorrect.
• A quadrilateral is a closed polygon with four sides, four angles, and four vertices. The total of these inner angles is always 360 degrees.
• A rectangle is a closed two-dimensional polygon having four sides, four angles, and four vertices. The diagonal sides of the rectangle are identical in length. Two lengths and two widths make up a rectangle.
The only quadrilateral with two lines of symmetry is a rectangle, according to Dave.
The line about which one part of a figure is mirrored to the opposite image is referred to as a quadrilateral with two lines of symmetry. A quadrilateral with two lines of symmetry takes on the shape of a rhombus. The form is reminiscent of a kite. As a result, the statement above is untrue.

The distributive property is basically expanding brackets.
So if you take 3(x + 4) = 36 and remove the brackets (so multiplying out the 3), you get:
3x + 12 = 36
And from there you simplify :)
3x + 12 = 36
3x = 24
x = 8
The distributive property was used to multiply the 3 through the brackets, thus making the equation easier to solve I guess

Answer:
Step-by-step explanation:Perhaps somebody's asked this already, but I can't see it. Suppose I have a square that is 7 feet by 7 feet. I want to calculate the area. I multiply 7 feet by 7 feet and get 49 square feet, but since the lowest number of sig figs in one of my operands is one, my answer can only have one sig fig. This forces my answer to be 50 square feet, and I have now lost precision. Can somebody explain this?
