F(3), replace r with 3
f(3)=3.14(3)^2=3.14(9)=28.26
f(3)=28.26
Answer: answer is C my fellow hooman
Step-by-step explanation:
Substitution!
<span>y = 4x – 10...(1)
y = 2...(2)
You have y=2 here, substitute it in equation (1),
</span><span>y = 4x – 10
</span><span>2 = 4x – 10
</span>Add both sides by 10
12=4x
Divide both sides by 4
x=3
We have x=3, and y=2. ==> (x,y) = (3,2)
I think it's 25. area is length times width aka...5 X 5 if you take the length times width of the tiles it's 1.
1x = 25 divide both sides by 1...
x ( number of tiles) = 25
