If x = 3k + 2 and y = k - 2 is a solution of linear equation 5x - 3y = 4 , then the value of k

Andrej [43]

Answer:

It is given that 5x−3y=k

Now by substituting the value of x and y in the equation

5(3)−3(4)=k

So we get

15−12=k

k=3

Therefore, the value of k is 3

Drag a statement or reason to each box to complete this proof. If −3(x+8)=−21, then x=−1.

Luda [366]

The answer is true because, you must use the distribute then add both sides by 24 then divide both sides by -3 and then you will come up with your answer x=-1 which means that statement is true

AD => Cos 20 = 12.6/H => H = 12.6/Cos 20 = 13.4cm

AB => √13.4^2 - 12.6^2 = 4.6 cm

BC = √19.3^2 - 12.6^2 = 14.6 cm

AC = 14.6 + 4.6 = 19.2 cm

Write the perimeter of each figure as a trinomial. Must show your work.

noname [10]

Answer:

P = 2n + 8m - 1

Step-by-step explanation:

A trinomial is an expression or equation that has three terms. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.

If two terms have the same variable, called like terms, they can be combined by addition or subtraction.

The perimeter is the total length of all the sides.

The formula for the perimeter of a triangle is $P = s_{1} + s_{2} + s_{3}$ for each of the three sides.
