A cuboid dimensions are given as 19.56 cm by 5.23 cm by 3.86 cm .by rounding each number to the nearest whole number estimate volume work given pleaee​

400

Step-by-step explanation:

19.56 gives 20

5.23 gives 5

3.86 gives 4

Volume= length*width*height=20*5*4=400

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
