Answer:

  • a=4
  • b=12
  • c=9
  • You have correctly selected the standard form.

Step-by-step explanation:

  (2x +3)² = (2x)² + 2(2x)(3) +(3)²

  = 4x² +12x +9

Comparing that to ax² +bx +c, we can identify ...

  • a = 4
  • b = 12
  • c = 9

artcher [175]

Answer:

Profit = 75

Step-by-step explanation:

Selling price of 3 oranges = 2

There are 210÷3 = 70 set of oranges

Selling price of 1 set (3 oranges) of orange = 2

Selling price of 70 set of oranges = 70 * 2 = 140

Cost of 210 oranges = 65

Profit = selling price - cost price

         = 140 - 65

         = 75

Add (1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2) For each term in the second polynomial, enter the letter showing where that term s
nignag [31]

Answer:

(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2) = 1.3t^3 + t^2 -42t  + 8

Step-by-step explanation:

Given

(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2)

Required

Solve

We have:

(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2)

Collect like terms

1.3t^3 + 0.6t^2 + 0.4t^2 - 24t- 18t  + 8

1.3t^3 + t^2 -42t  + 8

So:

(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2) = 1.3t^3 + t^2 -42t  + 8
