3+c - (4+c)
pretend that there is a -1 in front of the bracket
3+c-1(4+c)
multiply the bracket by -1
(-1)(4)=-4
(-1)(c)=-c
3+c-4-c
3-4+c-c ( combine like terms)
+c-c=0
3-4=-1
-1+0=-1
Answer:
-1
ok, so x is a number ranging from 40-90 which is 50 meaning that x has 50 different possibilities. But what are the chances that x is 75? well the chances of x being 75 is 1 out of 50.
so that means there is a 2% chance of x being 75

B, divide it’s coordinates in half. -5/2 and -1/2.
1. I am guessing the triangles split the bottom in half so you will find the area of the triangles and the rectangle and add them together
Triangle=3×4 /2 12/2=6
Triangle 3×4 /2 6
Rectangle: 8×1 8
6+6+8=
12+8=20m^2
2. Triangle area+rectangle area
Rectangle: 22×24 528
Triangle: 8×24 /2 192/2 96
528+96= 624
