Answer:

8 ft^2

Step-by-step explanation:

$\frac{h1}{2ft} =\frac{h2}{3ft} \\\\$

area of ABC is:

$A= \frac{(3ft)(h2)}{2}$

area of ABC is 18 square ft, then

$h2 = \frac{(area)(2)}{3ft} = \frac{(18 ft^2)(2)}{3ft} =12ft$

now you can find h1 and the area for EFG

A(3-x)=-2x+B if x=2 How do I find A and B what are the answers

irina1246 [14]

Answer:

$A=5,B=9\\\\or\ A=-9,B=-5$

Step-by-step explanation:

$A(3-x)=-2x+B\\\\Given\ x=2\\\\Substitute\ the\ value\ of\ x\\\\A(3-2)=-2\times 2+B\\\\A=-4+B\\\\A=B-4\\\\So\ the\ value\ of\ A\ is\ 4\ less\ than\ the\ value\ of\ B.\\\\When\ B=9\Rightarrow A=9-4=5\\\\When\ B=-5\Rightarrow B=-5-4=-9\\\\Hence\ A=5,B=9\\\\or\ A=-9,B=-5$
