Answer:
6b^2 +4b
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 * (3b+2) * (4b)
=1/2 (12 b^2 +8b)
= 6b^2 +4b

Answer:
72°
Step-by-step explanation:
The external angle E is half the difference of subtended arcs CG and DF.
E = (CG -DF)/2
2E = CG -DF . . . . . . multiply by 2
DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values
arc DF = 72°
Answer:
Option 4 is correct.
The equation
is equivalent to 
Step-by-step explanation:'
Given equation: 
First group the terms with x and those with y;

Next, we complete the squares.
We can do this by adding a third term such that the x terms and the y terms are perfect squares.
For this we must either add the same value on the other side of the equation or subtract the same value on the same side so that the equality is maintained.
⇒
or



Add 360 on both sides we get;

Simplify:

Therefore, the given equation is equivalent to 
Answer:
The answer is: 81%
Step-by-step explanation:
Divide 405 by 500 and multiply result by 100 to get percent.
405 / 500 = 0.81
0.81 x 100 = 81%
Hope this Helps!! Have an Awesome Day!!
