Answer:
b) 9x² - 3x
Step-by-step explanation:
Area of a rectangle = Length × Width
Area for the rectangle = 3x - 1 × 3x
Area = 
Step 1. Multiply by combining like terms
3x · 3x = 9x²
Step 2. Multiply -1 by 3x
-1 · 3x = -3x
Step 3. Combine 9x² and -3x
9x² - 3x

doomdabomb: All brainliest and thanks are appreciated
and would mean a lot to me, thanks!
a. 4 – commutative property
b. 5 – commutative property
c. 0 – identity property
d. 4 – associative property
_____
The commutative property lets you swap the order: (a) + (b) = (b) + (a).
The associative property lets you change the grouping: (a+b)+c = a+(b+c).
The identity property lets you add 0 without changing anything: (a) +0 = (a).
Answer:
1. A
2. H
3.B
4. H
5. A
Those are the answers
Step-by-step explanation:
1. 30 - 2(-8)= 46
2. BODMAS applied 6-7 =-1
3. 45/-5=-9
4. Sum is h +73
5.BODMAS applied 60 /6 = 10
Third angle = 180 - (44 + 72) = 180 - 116 = 64 degrees answer
B
Its because when you rearrange using this formula y=mx+c, where m is slope, if m is negative then that line has a negative slope
