expand the following: 4(2x+1)​

Answer:

supplementary

vertical angles

sub

Step-by-step explanation:

The missing reasons for the given two column proof are respectively;

Reason 2; Definition of Supplementary angles

Reason 3; Substitution Property of Equality

Reason 4;Subtraction Property of Equality

From the two column proof, we are given that;

m∠2 = m∠3

Now, for m∠1 + m∠2 = 180°, we see that m∠1 and m∠2 are on a straight line and we know that angles on a straight line sum up to 180°. Thus, the reason is because they are supplementary angles.

Similarly, m∠3 and m∠4 are on a straight line and as such;

m∠3 + m∠4 = 180°

m∠1 + m∠2 = m∠3 + m∠4. This is true because of substitution property of equality.

Lastly, since m∠2 = m∠3, then it means that they will cancel out in the statement 3 and as such we now have;

m∠1 = m∠4. The reason is subtraction property of equality

Step-by-step explanation:

{60°, 300°}

Using the half angle identity:

[tex]\sin\left(\frac{x}{2}\right)+\cos\left(x\right)-1=0\\\sin\left(\frac{x}{2}\right)+1-2\sin^{2}\left(\frac{x}{2}\right)-1=0\\\sin\left(\frac{x}{2}\right)-2\sin^{2}\left(\frac{x}{2}\right)=0\\\sin\left(\frac{x}{2}\right)\left(1-2\sin\left(\frac{x}{2}\right)\right)=0\\[/tex]

Using zero product rule:

[tex]\sin\left(\frac{x}{2}\right)=0,\frac{1}{2}\\x=\frac{x}{2}=0,30,150,180\\x=0,60,300,360[/tex]

Since, 0° ≤ x < 360°, so, x=60,300

Answer:

(x+20) + (x-9)

Step-by-step explanation:

Answer:because 6, 10, and 5 equal 21

Adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

Given that, adding 6, 10, and 5 to a number the same as adding 21 to that number.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the unknown number be x.

Add 6, 10, and 5 to x, we get x+6+10+5 = x+21

Add 21 to x = x+21

So equation is x+21 = x+21

Therefore, adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

Answer:

The absolute maximum value of f on [-2, 4] occurs at x = 4.

Step-by-step explanation:

We know that the absolute maximum value of f(x) on this interval will occur at either a critical point or an endpoint. The critical points are any point where f'(x) is either equal to zero or not defined. Since f is a polynomial, f'(x) = 3x^2 - 6x is always defined, but is equal to zero at x = 0 and x = 2. We can check the value of f(x) at each critical point and endpoint:

f(-2) = -8

f(0) = 12

f(2) = 8

f(4) = 28

Therefore, f has an absolute maximum value of 28 on the closed interval [-2, 4], which occurs when x = 4.
