Answer:

-4x² - 5(x + 3) + x²

= -4x² - 5x - 15 + x²

= -3x² - 5x - 15

Sara's by one whole

The smallest number is 55 between 55, 57 and 59.

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Let three consecutive odd numbers are n, n+2 and n+4.

The sum of three consecutive odd numbers is 171.

So,

Adding all three numbers,

n + n+2 + n+4 = 171

3n + 6 = 171

3n = 171 -6

3n = 165

n = 165/3

n = 55

And the other two numbers are 55+2 = 57 and 55+4 = 59.

And smallest number is 55 between 55, 57 and 59.

Therefore, the smallest number is 55.

Answer:

The value of cosA = (√3)/2 and tanA = 1/√3 or (√3)/3.

Step-by-step explanation:

Firstly,youhavetofindthevalueofadjacentusingPythogoras'Theorem,a²=b²+c²:

Let a = 2, b = 1

2² = 1² + c²

c² = 2² - 1²

= 4 - 1

= 3

c = √3

NowwehavefoundtheadjacentsowecanfindcosAandtanAusingTrigonometricfunction,cosθ=adj./hypo.andtanθ=oppo./adj.:

adj. = √3

oppo. = 1

hypo. 2

cosA = (√3)/2

tanA = 1/√3 OR (√3)/3
