Three students attempt to define what it means for lines lll and mmm to be perpendicular.
Vanyuwa [196]

Please find diagram attached

Answer and explanation:

Perpendicular lines are lines that meet at 90 degrees/ right angle.

The question seems to be incomplete but I will explain what perpendicular lines are in the context of lines lll and mmm, with some assumptions about the lines.

Assume that line III is 30mm long and line mmm is 25mm long, we say that line III is perpendicular to line mmm if line III meets line mmm at 90 degrees as we see in the diagram attached.

Solve for f. 2+1.25f=10-2.75f2+1.25f=10−2.75f
Ne4ueva [31]
We have to solve for f:
2 + 1.25 f = 10 - 2.75 f
1.25 f + 2.75 f = 10 + 2
4 f = 12
f = 12 : 4
f = 3
Answer: f = 3

sdas [7]

Answer:

135 square ft.

Step-by-step explanation:

To solve this equation, you need to find the area of this rectangle. Area is always base x height, or in this case, length x width. Now you multply your length, 15', by your width, 9', to get your answer, 135 square feet. When you multiply two measurments of the same unit together, you get square (units), which simply means that you multiplied two of the same unit of measurment together.

Which of the following shows the Commutative Property of Addition? (4 + 3) + x = (3 + 4) + x ab = ba r + (s + t) = (r + s) + t n
Novosadov [1.4K]
Commutative says you can add or multiply in any order

basically goes like this
a+b=b+a or
ab=ba

so what we need is something where the order change, nothing else
first one: (4+3)+x=(3+4)+x, the order changed, correct

2nd
ab=ba, this is not addition

3rd
r+(s+t)=(r+s)+t this is associative property

4th
n+0=n
this is zero addition property



answer is first one
