3(2x - 4) - 6(x - 3)
Distribute the 3 and the -6
6x - 12 -6x + 18
Combining like terms the expression simplifies to 6
Answer:
49 pi
Step-by-step explanation:
I'll assume you want to know how big the carpet is. You need to find the area of the room, which is a circle. The area of a circle is given as pi*r^2, where r is the radius. The diameter is twice the radius, so as the problem gives us a diameter of 14, the radius would be 7. Plug in 7 for r, and we get 49pi.
Answer:
C. 70 in^2
Step-by-step explanation:
What you do is use the formula for finding the area of a trapezoid.
A=a+b/2(h).
a=8
b=12
h=7
A=8+12/2(7)=70 in^2 is your answer.
Woahh thats a lot of points!! Thank you!!!!
Answer:
1 4/25 - 3/5, or 29/25 - 3/5, or 
it doesn't really matter they all mean the same
Step-by-step explanation:
1 2/5m - 3/5(2/5m + 1)
multiply first
1 2/5m - 6/25m - 3/5
multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.
1 10/25m - 6/25m - 3/5
add/subtract
1 4/25m - 3/5
