Factor 7a^3+28a^2-35a

Answers

Answer 1

Answer: $7a^3+28a^2-35a=7a(a^2+4a-5)=(*)\n \n-------------------------------\n \na^2+4a-5-a^2-a+5a-5=a(a-1)+5(a-1)=(a-1)(a+5)\n \n-------------------------------\n \n(*)=7a(a-1)(a+5)$

Answer 2

Answer: $7a^3+28a^2-35a =\n \n=7a(a^2+4a+a-a-5) =\n \n= 7a(a^2+5a -a-5)=\n \n=7a[(a(a+5)-(a+5))]=\n \n=7a(a+5)(a-1)$

Graph the equation x-y=6

Answers

$x-y=6\n\nThe\ slope-intercept\ form:y=mx+b\n\n-y=-x+6\ny=x-6\n\ny-intercept\ (x=0)\ny=0-6=-6\n(0;-6)\n\nx-intercept\ (y=0)\n-x+6=0\nx=6\n(6;\ 0)$

x-y-6=0 is the standard form you can graph this by using the y-x intercept form
x-intercept y=0
x-6=0
x=6
y-intercept, x=0
-y-6=0
-y=6
y=-6
therefore you can plot points on (0,-6) and (6,0) ad connect them together

Which of Polygons B, C, D, E, and F are similar to Polygon A?

Answers

Similar polygons have congruent angles and proportional sides, which mean they have the same shape but not necessarily the same size. It's important to focus on the shapes, angles, and proportions when identifying similar polygons. Frequency polygons, though a type of polygon, are related to data representation not geometric comparison.

In order to determine which polygons are similar to Polygon A, one would need to compare the shapes and proportions of the polygons.

Similar polygons have the same shape, but not necessarily the same size. They have congruent angles and proportional sides.

This concept stems from geometry, a branch of mathematics that studies shapes and spatial relationships among different shapes.

Frequency polygons are used in data representation, and they are not directly relevant to determining similarity between geometric polygons.

They are more related to statistics, a different branch of mathematics, and are used to show the distribution of a set of data, often overlaying different data sets for comparison.

Remember, when looking for similar polygons, focus on the shapes, angles, and proportions, not the size. Without seeing the actual diagrams of Polygons B, C, D, E, and F, we cannot definitively say which are similar to Polygon A.
