 An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the trian

gle is (y+4). Another side is 3 less than
2 times the length of the bottom of the triangle. The last side is 2 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

<span>length of the bottom of the triangle = (y+4)
</span><span>Another side is 3 less than 2 times the length of the bottom of the triangle = 2(y+4)-3
</span><span>last side is 2 more than the bottom of the triangle = (y+4) + 2
perimeter of triangle = sum of all the sides of triangle
So, the expression for perimeter of this triangle is;
P = (y+4) + </span>2(y+4)-3 + (y+4)+2
Now, simplify this;
P= y+4+2y+8+y+4+2
P=4y+18

The points (6, -3) and (7, -10) fall on a particular line. What is its equation in point-slope form? Use one of the specified po
kumpel [21]

Answer:

Step-by-step explanation:

Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Get the slope;

m = Δy/Δx = y2-y1/x2-x1

m = -10-(-3)/7-6

m = -10+3/1

m = -7

Get the intercept;

Substitute the point (6, -3) and m = -7 into the expression y = mx+c

-3 = -7(6)+c

-3 = -42 + c

c = -3 + 42

c = 39

Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c

y = -7x + 39

Hence the required equation is y = -7x + 39

58 to x should be the ratio of 6/3 or 1/2 if they are similar.

Find out how much bigger 58 is compared to 6, the matching side on the other polygon.

58/6 = ~9.7

The x side should be half of this, just like it is on the smaller polygon.

9.7/2 = 4.85

4.85 x 3 = 14.55

Answer:

  11

Step-by-step explanation:

Put 3 where x is and do the arithmetic.

  g(x) = x² +2

  g(3) = 3² +2 = 9+2

  g(3) = 11
