:) solve for x to the nearest tenth. x^2+x-5=0

1.8, -2.8

Step-by-step explanation:

1.8, -2.8 in decimal form rounded to the nearest tenth.

In quadratic form its originally

Hope this helps

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

the answer is 62.8 cubic units
