(a-b-2)(3a-3b-4) is your answer

Answer:

3(a-b)²-lo (a-b) +8

let (a-b) be x

3x²-10x+8

doing middle term factorization

3x²-6x-4x+8

3x(x-2)-4(x-2)

(x-2)(3x-4)

substituting value of x

(a-b-2)(3(a-b)-4)

(a-b-2)(3a-3b-4)

X = 38°

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

Then.. :

136+ x= 180

180- 136= x

X= 44

88 + 44 + x = 180

142+ x = 180

X= 180-142

X = 38°

Find an​ nth-degree polynomial function with real coefficients satisfying the given conditions calulator?
fgiga [73]

Answer:

Degree = 4

Step-by-step explanation:

For the given conditions:

n = 4

i and 5i are zeros

f(-2) = 145

For zeros, it means they are a quadratic factor of the expression

It means, we will have x = ± i and x = ± 5i

therefore, the given factors are (x - i)(x + i)(x - 5i)(x + 5i)

Hence, we have the function

given degree = 4

f(x) = a(x-i)(x+i)(x-5i)(x+5i)

f(x) = a(x² + 1)(x² + 25)

Hence, substituting -2 for x, we have

f(-2) = a(5)(29) = 145

Hence, a = 1

f(x) = x⁴ + 26x² + 25

Therefore, we can see that the given degree = 4

Answer:

1a) t = 0.17b

1b) $36.03

2) 51,167.50

Step-by-step explanation:

1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip

1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.

To find what the cost was without the tip, divide the bill total by 1.17

248/1.17 = 211.97. That was the bill before the tip was added.

248-211.97 = 36.03 was the tip added.

2) 5.5% converted to a decimal is 0.055

0.55 x 48,500 = 2667.50

$2,667.50 + $48,500 = 51,167.50

Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500

1.055 x 48,500 = 51,167.50
