X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
Ma’am the answer is 8
Please finis
Area is length times width.
Just some more info, volume is length times width times height.
Hope this helps!
Answer:
to see which one is greater you can divide 9/1 and 8/10 into decimals and see which one is the greatest
9/1 = 9
8/10 = 0.8
9/1 > 8/10
Answer:
10.2π
Step-by-step explanation:
Given data
Area of circle= 81 ft^2
Also, the expression for the area of a circle is
A=πr^2
substitute
81=3.142*r^2
r^2= 81/3.142
r^2= 25.77
square both sides
r= √25.77
r= 5.1
Also, the expression for the circumference is
C= 2πr
substitute
C= 2*π*5.1
C= 10.2π
Hence the circumference is 10.2π
