Step-by-step explanation:
- CASE 1:2x(3x+7) = 6x^2+14x.
- CASE 2:(2x + 3)(3x – 1)
- CASE 3:x2 + 4x
Answer:
=
Step-by-step explanation:
Expression given is:
Now change the mixed fraction to improper fractions;
Now take a common denominator:
Now we can simplify the the above equation:
=
Line segment and ray are defined terms
Point, line, and plane are undefined terms because they have not thickness or width
A) Vectors are usually given in the form (x , y), therefore the x-component of v is 1.
B) Similarly to point A), the y-component of w is 6
C) the magnitude of the vector v+w is given by:
√[(x₁ + x₂)² + (y₁ + y₂)²] = √[(1 + (-2))² + (-3 + 6)²] = √(1 + 9) =√10
D) Compute -2 · v = (-2·1 , -2·(-3)) = (-2 , 6) = w
Therefore options B) and D) are true.

Step-by-step explanation:
3.14× 6² =226.08
3.14× 6×40 = 753.6
753.6 + 226.08 = answer stated above
