We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
Answer:
1. Infinitiely many solutions, one solution, no solutions
2.
y=-3/2x-4
y= x+1

Answer:
9ab+3a
Step-by-step explanation:
2a*3b=6ab
2a*1=2a
a*3b=3ab
a*1=a
adding everything together=6ab+2a+3ab+a=9ab+3a
Answer:
<h2>x + 2y = 8</h2>
Step-by-step explanation:
The standard form of an equation of a line:

We have:

Convert:
<em>multiply both sides by 2</em>
<em>add x to both sides</em>

Answer:
The correct answer would be 64 because 8 times 8 would be 64 therefore the answer is 64
