Answer:

  8m³ -4m² +3m

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.

  P = side 1 + side 2 + side 3

  18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3

  18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms

  18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)

  m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms

  8m³ -4m² +3m = side 3

Answer:

1.8m²

Step-by-step explanation:

∅= 51× π/180 = 17π/60

area of sector= 1/2 × r²× ∅

= 1/2 × 2²× 17π/60

= 34π/60

= 1.78m²

A curve has the slope 2x+3 at each point (x,y) on the curve. What is an equation for this curve if it passes through the point (
yawa3891 [41]
Therefore, f(x) = 2x + 3 is your derivative function, and you need to find the original curve. So find the antiderivative using the given conditions... 

∫f(x) = ∫2x + 3 dx 
F(x) = x^2 + 3x + C 
2 = (1)^2 + 3(1) + C 
2 = 4 + C 
C= -2 

Therefore, the curve is F(x) = x^2 + 3x - 2 

Proof: The derivative is the slope at every (x, y) point. The derivative of F(x) comes out to be 2x + 3, so we have found the curve. Plug in x = 1, and y = 2, so the conditions have been met.
