2a2 + -1 2-a) +36 ; a=5, b=0

the answer is 39

Step-by-step explanation:

hope that helps

Hey mate

Step-by-step explanation:

This is ur answer

2a2 + (-1×2-a) +36

= (2×5×2) + (-1×2-5) + 36

= 20 + (-7) + 36

= 56 + (-7)

= 56 - 7

= 49

Hope it helps you,

Mark me brainliest pls...

Follow me ;)

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

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
