More than means addition.
C is the correct option.
= (2x + 4) + 9 - 4y + 3x
= 2x + 4 + 9 - 4y + 3x
= 5x + 13 - 4y
= 5x - 4y + 13
Answer:
Step-by-step explanation:
As the triangles are similar :
45/55 = (12x - 3)/143
9/11 = (12x - 3)/143
9 x 13 = 12x - 3
12x = 117 + 3
12x = 120
x = 10
Answer:
20 square units
Step-by-step explanation:
If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.
Answer:
x=
−399
/75
Explanation:
Step 1:
−34(8x+12)=3(x−3)
(−34)(8x)+(−34)(12)=(3)(x)+(3)(−3)(Distribute)
−272x+−408=3x+−9
−272x−408=3x−9
Step 2:
−272x−408−3x=3x−9−3x
−275x−408=−9
Step 3:
−275x−408+408=−9+408
−275x=399
Step 4:
−275x
−275
=
399
−275
