Given : f(x) = 3x + 1
We get f(2) by substituting x = 2 in the given Function
⇒ f(2) = 3(2) + 1
⇒ f(2) = 6 + 1 = 7
Option C is the Answer
The area of a circle is π (Pi) times the Radius squared, which is written:
A = π × r2
Or, when you know the Diameter:
A = (π/4) × D2
Or, when you know the Circumference:
A = C2 / 4π
C=2b
d=c+7
b+c=57⇒b+2b=57⇒3b=57⇒ b=19, c=2*19=38, d=38+7=45
thats given
lets find if there is an x such that d-x=b+x=c⇔ 43-x=19+x=38
43-x=38⇒x=43-38=5
19+x=38⇒x=19
there is no single x (cant be both 5 and 19)
so, i think dan was incorrect.
The sum of angles inside a triangle is the sum of angles 1, 2 and 3, which form a straight line, therefore 180 degrees.
The sum of the exterior angles
angle exterior angle
1 2+3
2 1+3
3 1+2
total 2+3+1+3+1+2=2(1+2+3)=2(180)=360 degrees.
Okay, so the pattern is multiplying by 4. so to find the next two numbers: 128 times 4=512 times 4=2048. so all six numbers are 2, 8, 32, 128, 512, and 2048. Add all six together and you get D-2730.
