Answer:

5x+1

Step-by-step explanation:

the perimeter is the outside values of the shape, and we know all the values, so we just have to add them all up.

(x+4) + (2x-1) + (3x-2) = perimeter

since it's all subtraction and addition we can remove the parentheses

x+4+2x-1+3x-2 = perimeter

now let's put all the x's on one side and the numbers on the other side to make it easier

x+2x+3x+4-1-2= perimeter

5x+1

Answer:

Perimeter of the triangle is :---

(x + 4) + (3x - 2) + (2x + 1) \\ = x + 4 + 3x - 2 + 2x + 1 \\ = \boxed{(6x + 3 )\: ft }

<h3><u>(6x+3) ft</u> is the right answer.</h3>

vodomira [7]

Answer:

x = 25.8^{o} and y = 51.4^{o}

Step-by-step explanation:

Known that he sum of angles on a straight line is 180^{o}. From the diagram;

2y + x + y = 180^{o}

x + 3y = 180^{o} ................ 1

Also,

2x + x + 2y = 180^{o}

3x + 2y = 180^{o} .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = 180^{o} ............. 4

7y = 360

y = \frac{360}{7}

y = 51.4^{o}

substitute the value of y in equation 1,

x + 3y = 180^{o}

x + 3(51.4) = 180^{o}

x + 154.2 = 180^{o}

x = 180^{o} - 154.2

x = 25.8^{o}

Thus, x = 25.8^{o} and y = 51.4^{o}

LenaWriter [7]

Answer:

n=0.3

Step-by-step explanation:

divide the numbers

0.2/n=0.4/0.6

0.2/n=.066666

then you multiply by the same dominator to both sides

n*.02/n=n*.066666

Cancel multiplied terms that are in the denominator

0 . 2 =
