Answer:
-175
Step-by-step explanation:
5x4=20
30x2=60
20-60=-40
-40-135=175
I hope this helps!
(-6,-4)
If you dilate a point, (c,d) about (a,b) by a scale factor by k. You'll going to subtract each coordinates where the point will be dilated about (a,b) from the point (c,d) and then multiply them by k. This would be the formula if you want: (k(c -a), k(b -d))
Let's say F is the dilation of D about the origin or (0,0) then the x coordinate of F would be

This would be the y coordinate of F:

Thus the coordinates of F is (-6,-4)
Answer:
27.93 square yard
Step-by-step explanation:
For semicircle:
Radius (r) = 7 yards
For Triangle:
b = 2r = 2*7 = 14 yd
h = 7 yard
Area of shaded region = Area of semicircle - Area of triangle

A)answer: A cross section is the two-dimensional shape that results from cutting a three-dimensional with a plane.
B)answer: A cross section is the face you obtain by making a "slice" through a solid object. A cross section is two-dimensional. ... When a plane intersects a solid figure, the cross sectional face may be a point, a line segment, or a two-dimensional shape such as, but not limited to, a circle, rectangle, oval, or hexagon.
