Answer:
181.12 mm²
Step-by-step explanation:
12.8 x 28.3 = 362.24
362.24 ÷ 2 = 181.12
Y=2x+5
Parallel lines have the same slopes, so you only change the 3 to a different number.
You want to start the equation like Y=2x then any number at the end.
This can vary, some shapes have different area formulas, here are some basic formulas I can give you:
Circle: A =
Triangle: A =
Square: A =
Rectangle: A = L*W
-6x -17 ≥ 8x + 25
Subtract 8x from each side:
-14x -17 ≥ 25
Add 17 to each side:
-14x ≥ 42
Divide each side by 14 :
-x ≥ 3
Change the signs. (Multiply each side by -1.)
That's when you have to flip the inequality symbol.
x ≤ -3
C. 200
They earn $2.50 per box of markers, meaning that to make $500 they have to sell 200. [500/2.5=200]
