Answer:

6. n -8

7. 2 (15+n)

8. 30 + 3n^ 2

Step-by-step explanation:

6 is n-8 because decrease means subtraction

7. Twice the sum means multiplied by 2 sum means addition and a number is the unknown so if we put it together we get 2( 15+n)

8. I'm not sure about 8 but pretty much increased means addition times mean multiplication and twice could be the exponent.

Hope this helps:)

Answer:

6. -8 + n

8. 2[15 + n]

10. 30 + 3n²

Step-by-step explanation:

10. Three times the square of a number → 3n²

Increased by 30 → 30

8. The sum of 15 and a number → 15 + n

Twice the sum → 2[15 + n]

6. A number → n

Decreased by 8 → -8

** The above answer is written in reverse, which is the exact same result.

The sum of three numbers is 24. Twice the middle number is 2 more than the largest number, and the largest number is equal to th

harina [27]

Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

Let the numbers be x, y and z

x + y + z = 24
2y = z + 2
z = x + y

Solving by substitution:

x + y + z = z + z = 24
2z = 24
z = 12

2y = z + 2
2y = 12 + 2
2y = 14
y = 7

z = x + y
x = z - y
x = 12 - 7 = 5

The answer:

x = 5, y = 7, z = 12

Degree 4; zeros: -4+5i, -1 multiplicity 2

Kazeer [188]

Answer:

$f(x) = [x^{2} + 8x + 41](x + 1)^{2}$

Step-by-step explanation:

If -4 + 5i is a root of a polynomial, then it's conjugate -4 - 5i will also be a root of the same polynomial.

Therefore, the polynomial has 4 degree, and zeroes are (- 4 + 5i), (- 4 - 5i) and -1 with multiplicity 2.

Hence, the polynomial will be

$f(x) = (x + 4 - 5i)(x + 4 + 5i)(x + 1)^{2}$

⇒ $f(x) = [x^{2} + 8x + (4 - 5i)(4 + 5i)] (x + 1)^{2}$

⇒ $f(x) = [x^{2} + 8x + 41](x + 1)^{2}$ (Answer)
