<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.
</span><span>Identity for multiplication is 1, for addition its 0</span>
Answer:
[see below]
Step-by-step explanation:
Using the Pythagorean Theorem:
Hope this helps.
6(3m + -5n + 7)
Distribute the 6.
6*3m + 6*-5n + 6*7
Simplify each individual term.
18m -30n + 42
Angle A would be 40 degrees I’m sure because it is a rotation not a dilation (which changes the measurements including the lengths and degree of angles)
Hope I helped :)
