Answer:
x = -1.4375
Step-by-step explanation:
Multiply the monomials: 40x + 7 = 24x - 16
Rearrange unknown terms to the left side of the equation: 40x-24x=-16-7
Combine like terms: 16x=-16-7
Calculate the sum or difference: 16x = -23
Divide both sides of the equation by the coefficient of variable: x = -23÷16
Calculate the product or quotient: x=-1.4375

Answer:
Solution: x³ + 3x² + 3x + 1
Step-by-step explanation:
Take a look at the following Pascal's Triangle:
(x + y)⁰ = 1
(x + y)¹ = 1x + 1y
(x + y)² = 1x² + 2xy + 1y²
(x + y)³ = 1x³ + 3x²y + 3xy² + 1y³
(x + y)⁴ = 1x⁴ + 4x³ + 6x²y² + 4xy³ + 1y⁴
As you can see our binomial is '(x + 1)³.' Therefore we expand the expression with respect to the third row in the Pascal's Triangle, (x + y)³ = 1x³ + 3x²y + 3xy² + 1y³. The procedure would be as follows:
(x + 1)³ = 1x³ + 3(x)²1 + 3x(1)² + 1(1)³ = x³ + 3x² + 3x + 1
