vlabodo [156]

Answer:

Help plz with Algebra question I attached a file

astraxan [27]

Answer:

x=4.63

Step-by-step explanation:

Area = (1/2) (base) (height)

20 = (1/2) (x+4) (x)

40 = x²+4x

x²+4x-40=0

Put in quadratic equation:

x= $\frac{-4(+/-)\sqrt{4^{2}-4(1)(-40) } }{2(1)}$

x= $\frac{-4(+/-)\sqrt{176} }{2}$

x=4.63324958071 or x=-8.63324958071

Since x can't be negative in this case we take our answer to be 4.63324958071, which rounds to 4.63
