Work: divide by 5
Answer:
2 1/3
Step-by-step explanation:
you have to take away 3 1/4 and 1 2/3
Answer:
option D
Step-by-step explanation:
f(x) = 7x- 3
g(x) = x2 - 4x- 8
we have
(f+g)(x)= 7x- 3 +x2 - 4x- 8
(f+g)(x)= x2+ 3x- 11
Answer: all of the above
Step-by-step explanation:
Answer:
D: 108 cm
Step-by-step explanation:
Use your test-taking skill to eliminate the other answers. The perimeter of the given square is (9 cm)×4 = 36 cm. None of the other answers can possibly be correct for a square that is made larger by dilation.
_____
Every linear measure is increased by the dilation factor. If side lengths are multiplied by 3, then the perimeter is multiplied by 3.
... 3×36 cm = 108 cm
____
Another way to ge there is to realize the side length is multiplied by 3, so in the larger square is 3×9 cm = 27 cm. The perimeter is the the sum of the 4 equal sides, so is ...
... 4×27 cm = 108 cm
