Answer: 7.29π mm²
Step-by-step explanation:
First, I am assuming XY is the diameter of the circle :)
The formula for the area of a circle is πr² (r = radius)
So that means we need to divide the diameter by 2 to find the radius
5.4 / 2 = 2.7
Now we simply plug in our numbers!
3.14 · 2.7²
3.14 · 7.29
And that's it!
Hope this helped you :)
The last number line the correct answer!
-2a-5>3
-2a>8
a<-4
( the sign is flipped in the end because when you multiply or divide by a negative number, the sign flips the other way around)
Answer:
3x2y−3xy+12x−12
Take out 3xy common from first two terms and 12 from last two terms.
3xy(x−1)+12(x−1)
(x−1)(3xy+12)
First you combine the like terms which are the Ws.
And if there's no number in front of the variable (w in this case) it
Answer:
x = 1
Step-by-step explanation:
Were trying to solve for x so we would say 3 1/2 - 2 1/2 and we would be left with 1. So x=1, which you then substitute into the problem to make sure it's correct so 2 1/2 + 1 = 3 1/2.
Hope this helped
