127

Step-by-step explanation:

(19-7)^2

(12)^2

=144

144-8×3+4×3-5

8×3=24

4×3=12

144-24+12-5

144+12-24-5

127

hope this helps

Step-by-step explanation:

Following the Order of Operations, we should subtract 19 - 7 = 12

Then, you do the exponents so, 12 * 12 = 144.

Next, multiply. 8 * 3 = 24 and 4 * 3 = 12

So your equation should look like this. 144 - 24 + 12 - 5

Now from left to right you solve it so, 144 - 24 = 120

144 - 24 = 120

120 + 12 = 132

132 - 5 = 127

Have a wonderful day!

step-by-step explanation:

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
