Answer:
- 2x - 24
Step-by-step explanation:
(x + 9)(x - 2) - 9x - 6
- 2x + 9x - 18 - 9x - 6 Multiply.
- 2x - 24 Combine the like terms.
Answer:
Step-by-step explanation:
1/2 + 6/7 + 2/9 = 199/126
378
x 6
six is your base number.. then you do 6x8 which is 48 you will leave the 8 under the ones column and carry the 4 above the seven then you do 7x6 plus the 4.
I think that's how i learned it

Answer:
2 a
Step-by-step explanation:
Possible derivation:
d/dx(2 a x + 2 a y)
Differentiate the sum term by term and factor out constants:
= 2 a (d/dx(x)) + d/dx(2 a y)
The derivative of x is 1:
= d/dx(2 a y) + 1 2 a
The derivative of 2 a y is zero:
= 2 a + 0
Simplify the expression:
Answer: 2 a
Step-by-step explanation:
Area for a right angle triangle = 1/2 bh
b = Base
h = Height
A = 1/2×bh
= 1/2 × 2c^3d^2 × 4c
= (2c^3d^2 × 4c) / 2
= c^3d^2 × 2c
= 2c^4 × d^2
