Answer:
(x^3+3x^2+x+1)+(2x^3-2x^2-2x+2)
3x^3 + x^2 - x + 3
I think I simplified it completely. Hope this helps! Good luck! :)
Answer:
im not sure but i think i hvae the answer in my phone but it has to chrge
Step-by-step explanation:
Answer:
28 cm²
Step-by-step explanation:
The area of Δ BDF is the area of the rectangle subtract the area of the 3 white triangles.
Since the area of the rectangle = 80 cm² and
area = length × breadth, then
breadth = 80 ÷ 10 = 8 cm
Thus CE = EF = 8 cm and CD = DE = BC = 4 cm
Area of Δ DEF = 0.5 × 10 × 4 = 20 cm²
Area of Δ ABF = 0.5 × 8 × (10 - 4) = 0.5 × 8 × 6 = 24 cm²
Area of Δ BCD = 0.5 × 4 × 4 = 8 cm²
Thus
area of Δ BDF = 80 - (20 + 24 + 8) = 80 - 52 = 28 cm²
Then for number 3 put a plot at 4 then one at negative2 and draw yor line
Answer:
-3/4
Step-by-step explanation:
You can use the rise over run method to calculate between the 2 points or y2-y1 over x2-x1. Both methods will work.
