Explain (1+y)^2 how does it turn into 1+2y+y^2 ? i don't understand
Greeley [361]
I will show you the steps on how you get that answer and if you have any questions after that let me know and I'd be more than happy to help answer them for you.
The first step for solving (1 + y)² is to use the equation (a + b)² = a² + 2ab + b² to expand the expression.
1² + 2 × 1y + y²
1 raised to any power equals 1,, so remove the power.
1 + 2 × 1y + y²
Calculate the product of 2 × 1y.
1 + 2y + y²
Finally,, use the commutative property to reorder the terms.
y² + 2y + 1
Let me know if you have any further questions.

Sin(angle) = opposite leg / hypotenuse

Sin(45) = Opposite leg / 28

Opposite Leg = 28 * Sin(45)

Opposite Leg = 14 SQRT(2) = 19.8

Answer: 2 4/9

The decimal equivalent is 2.44

Step-by-step explanation:

It may help to convert the fractions to decimals. Divide the numerator by the denominator.

2 3/8 is 2.375

2 1/8 is 2.125 etc.

Remember that absolute value is considered positive. Then put the numbers in order.
