If its -26 degree in Canada and 34 degrees in Australia what is the difference in temperature

Answers

Answer 1

Answer:

It would be 60 degrees

Step-by-step explanation:

You take the numbers and write the equation 34-(-26) to figure out the difference. You then change the signs, making it 34+26, as before you were subtracting a negative. If you complete that problem, you come to the conclusion of 60.

What is the factored form of this expression?
-9x^3 - 12x^2 - 4x

A. x(3x - 2)(3x + 2)

B. -x(3x + 2)^2

C. x(3x - 2)^2

D. -x(3x - 2)(3x + 2)

Answers

Answer:

B

Step-by-step explanation:

Given

- 9x³ - 12x² - 4x ← factor out - x from each term

= - x(9x² + 12x + 4) ← perfect square

= - x(3x + 2)(3x + 2)

= - x(3x + 2)² → B

-9x^3-12x^2-4x

Factor out -x from the expression

-x×(9x^2+12x+4)

Using a^2+2ab+b^2=(a+b)^2 Factor the expression

-x×(3x+2)^2

now we do the same thing only different way ok

9x^2+12x+4

write the number in the exponential form with an exponent of 2

3^2 x^2+12x+4

write the expression as a product with the Factors 3x and 2

3^2 x^2 +2×3x×2+4

write the number in the exponential form with an exponent of 2

3^2 x^2+2×3x×2+2^2

Multiply the terms with equal exponents by multiplying their bases

(3x)^2+2×3x×2+2^2

Using a^2+2ab+b^2=(a+b)^2 Factor the expression

(3x+2)^2

Solution: -x×(3x+2)^2

answer:B

Answers

Answer:

36

Step-by-step explanation:

Hello,

If [tex]X=x^2[/tex] it becomes

[tex]X^3-289X^2-X+289=(X^2-1)(X-289)[/tex]

and [tex]289=17^2[/tex]

[tex]X^2-1=(X-1)(X+1)=(x^2-1)(x^2+1)=(x+1)(x-1)(x^2+1) \\\\x^2-289=x^2-17^2=(x-17)(x+17)[/tex]

So,

[tex]x^6-289x^4-x^2+289=(x^2-1)(x^2+1)(x^2-289)=(x-1)(x+1)(x+17)(x-17)(x^2+1)[/tex]

a = 1

b = 1

c = 17

d = 17

e = 0

Then a + b + c + d + e = 36

Write an equation in Standard Form of the line passing through (5, -4) with a slope of -2/5.

Answers

Answer:

The answer is

[tex]y = - \frac{2}{5} x - 2 \\ [/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the points is (5, -4) and slope - 2/5

The equation is

[tex]y + 4 = - \frac{2}{5} (x - 5) \\ y + 4 = - \frac{2}{5} x + 2 \\ y = - \frac{2}{5} x + 2 - 4[/tex]

We have the final answer as

[tex]y = - \frac{2}{5} x - 2 \\ [/tex]
