Answer:

3rd option

Step-by-step explanation:

the ratio of b : c is the cos77° , that is

cos77° = $\frac{adjacent}{hypotenuse}$ = $\frac{b}{c}$ ≈ 0.224951054.

dybincka [34]

If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:

-24 ≤ 3x - 9 First add 9 on both sides

-24 + 9 ≤ 3x - 9 + 9

-15 ≤ 3x Then divide 3 on both sides to get "x" by itself

$\frac{-15}{3} \leq \frac{3x}{3}$

-5 ≤ x [or x ≥ -5 if you prefer "x" to be on the left side]

What is the first step to 7(x – 4) = 84.

ss7ja [257]

Parenthesis according to the PEMDAS rule

So
7(x - 4) = 84

Would be

7x -28 = 84

Hope this helped :)

Which expression is equivalent to x^4 + 4x^2 - 45?

Nikitich [7]

Answer:

$( {x}^{2} - 5)( {x}^{2} + 9) = 0$

Step-by-step explanation:

The given expresion is

${x}^{4} + 4 {x}^{2} - 45 = 0$

We can rewrite this as:

$({ {x}^{2}) }^{2} + 4 {x}^{2} - 45 = 0$

We obtained a quadratic equation in x²

Let us split the middle term to get:

$({ {x}^{2}) }^{2} + 9 {x}^{2} - 5{x}^{2} - 45 = 0$

We factor by grouping to get:

${x}^{2} ( {x}^{2} + 9) - 5( {x}^{2} + 9) = 0$

We factor further to get:

$( {x}^{2} - 5)( {x}^{2} + 9) = 0$

The correct answer is A.
