Answer:
1. -4x < 8
2. 4x < 8
3. When something is done to one side of the equation, the same thing must be done to the other side. Dividing each side by -4 in part A would cause the sign to flip because the sign is always flipped when dividing by a negative. Because 4 in 4x (part B) is not negative, the sign is not flipped.

Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
= 
≈ 43.52 cm² ( to 2 dec. places )
252mmSquared
Step-by-step explanation:
28+28=56
74-56=18
18÷2=9
9×28=252
Answer:
x=1y
Step-by-step explanation:
Answer:
y= 2x
Step-by-step explanation:
The slope is 2
The y-intercept is zero because it intersects the origin so you do not need to right that.
Now just put it is slope-intercept form.
Hope you remember me because I just answered your other question 2 minutes ago! LOL :D
Can you please name me the brainiest in both of those answers. Thanks!
