Answer:

B and D

Step-by-step explanation:

When both sides of an equation are same then the equation has infinitely many solutions

x-3x=-2x+4

Both sides are not same.

LEts simplify the left hand side. cancel out 3 at the top and bottom

x- x = 0

0=0 , so the equation have infinitely many solutions.

$\frac{1}{3} x-3=4+2x$

Both sides are not same , so does not have infinite solutions

Cancel out 3 at the top and bottom

3x + 2 -x = 2+2x

2x+2 = 2+2x

Both sides are same , so the equation have infinitely many solutions.

$x-\frac{1}{3} x+2=0$

Both sides are not same .

*Find the area of the figure below. Use 3.14 for pi.<br><br> Area= square inches

alex41 [277]

Answer:

100.26

Step-by-step explanation:

You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.

This is what that would look like:

1. Divide 6 (the diameter) by 2 because $r=\frac{1}{2} d$

$r=\frac{1}{2} 6$

$r=3$

2. plug into the formula $A=\pi r^{2}$

$A=\pi 3^{2}$

3. square the 3

$A=\pi 9$

4. multiply 9 by 3.14 (pi)

$A=28.26$

This means the area of both the semi circles added together would equal 28.26

Then you would use the formula $A=lw$ to find the area of the rectangle

1. plug in the numbers given

$A= 12$ · $6$

2. solve

$A=72$

Then add the area of the semicircles to the area of the rectangle

$A=28.26+72$

to get the area of the entire figure:

$A=100.26$
