Answer
x = 18 cm
Step-by-step explanation:
Here, we want to calculate the value of x
let half of x = b
so b is the base of each right-triangle
As we can see, the triangle is isosceles
we can calculate the length of the base of one of the smaller right angled triangle and multiply by 2 to get the full x length
According to Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides
15^2 = 12^2 + b^2
225 = 144 + b^2
b^2 = 225-144
b^2 = 81
b = √81
b = 9
but x = 2b
x = 2(9)
x = 18 cm

Explain how feel about trump being impeached a second time this time for the mobs action
Answers
Answer:
Trump needed to be impeached for his words and actions that led to the mob action.
He created the atmosphere of distrust in the election results by making statements that the only way he could lose the election would be if there was massive fraud. Then, when he lost the election, he used that as "proof" that there had been fraud. That is distorted logic.
Many of Trump's followers believed his claim that he had won the election, and they came to Washington DC for the rally to support him. Many of them were prepared to commit acts of violence against the members of the Congress, the senators and Vice-president Pence to prevent them from counting the votes from the Electoral College. The Trump followers believed that he could continue as president if they literally fought for him.
They invaded the Capitol and terrorized the elected officials. People died in the attack. And it could have been much worse.
None of that would have happened if not for Trump deluding them, inviting them, and encouraging them.
He must be held accountable.
Step-by-step explanation:
Opinions matter. People should form them based on facts. Facts can be verified and checked. There is a difference between assertions and facts. People can make assertions that are not true. Maybe they are mistaken. Maybe they were confused. People can admit their mistakes and correct the errors.
Some assertions are delusional: the person who makes the statement actually believes something that is not based on facts, and cannot be convinced otherwise.
Some assertions are lies, spoken to deceive others; they deliberately hide or distort the truth.

. The total area of a rectangular mural has been extended by x feet. The expression to represent the area is 5.5(7.5 + x). Rewrite the expression using the Distributive Property.
Answers
Answer and Step-by-step explanation: Distributive Property describes how to solve expressions like a(b +c). According to the property, multiplying the sum of two or more numbers by a number will result in the same as multiplying each number and then add the products. For example:
11(2 + 4)
11(6) = 66 22 + 44 = 66
So, for the expression that represents the area:
5.5(7.5 + x) = 41.25 + 5.5x
As the expression has non-numerical terms, the distributive property will be multiply each term and then add the products.
The expressio for area of a rectangular mural is 41.25 + 5.5x.
y=5x-7
-3x-2y=-12
Find x
Answers
Answer:
11/6=x
Step-by-step explanation:
System of Linear Equations entered :
[1] y=5x-7
[2] -3x-3y=-12
Equations Simplified or Rearranged :
[1] y - 5x = -7
[2] -3y - 3x = -12
Graphic Representation of the Equations :
-5x + y = -7 -3x - 3y = -12
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 7
// Plug this in for variable y in equation [2]
[2] -3•(5x-7) - 3x = -12
[2] - 18x = -33
// Solve equation [2] for the variable x
[2] 18x = 33
[2] x = 11/6
// By now we know this much :
y = 5x-7
x = 11/6
// Use the x value to solve for y
y = 5(11/6)-7 = 13/6
Solution :
{y,x} = {13/6,11/6}

Answers
Answer:
-4/3.
Step-by-step explanation:
cos O = 3/5
Using Pythagoras to find the length of the side opposite the angle O:
As the cos of O is adjacent/ hypotenuse, Hypotenuse = 5 , adjacent side = 3 so
opposite side. = sqrt(5^2 - 3^2) = sqrt 16
= 4.
Now the tangent is negative in Q IV so
tan O = opposite / adjacent side = -4/3

Cos A 4/5 so the answer is d
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Remark
The tangent is described as the ratio of the side opposite the reference angle divided by the side adjacent to the reference angle.
In this case
The reference angle is B
The side opposite is AC and it has a value of 4
The side adjacent is BC and it has a value of 3
Hypotenuse
If you are finding either the sine or cosine of any angle, you need the hypotenuse.
AB^2 = 4^2 + 3^2 = 16 + 9
AB^2 = 16 + 9
AB^2 = 25
Take the square root of 25
AB = 5
Cos(A)
The cos(A) = adjacent / hypotenuse
Adjacent = AC = 4
Hypotenuse = AB = 5
Cos(A) = a/h
Cos(A) = 4/5 which is D
How do I find these equations using substitution y=-3x+5 and 5x-4y=-3 ?
Answers
Answer:
x=1
Step-by-step explanation:
you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.

5x+12x-20=-3
17x-20=-3
17x=17
x=1
Answer:
(1,2)
Step-by-step explanation:
1) To solve using substitution, first isolate one of the variables in one of the equations. However, the y in y = -3x + 5 has already been isolated, so we don't need this step. Instead, take that value of y and substitute it for the y in the other equation, 5x - 4y = -3. So, substitute -3x + 5 for the y in 5x - 4y = -3 and solve:
[tex]5x-4(-3x+5)= -3\\5x+12x-20=-3\\17x-20=-3\\17x = 17\\x = 1[/tex]
2) So, x = 1. Now, take that value of x and substitute back into any of the equations to find the y value. (I chose to substitute it into y = -3x + 5, but either choice is fine). So, substitute 1 for the x in y = -3x + 5 and solve:
[tex]y = -3(1)+5\\y = -3+5\\y = 2[/tex]
So, y = 2. Thus, by knowing both x and y values, the solution would be (1,2).

Let the equation of the line be x = y - 12
