Answer:
Reflection
Step-by-step explanation:
This transformation maps the triangle on the other side of the quadrant.
The size of the triangle did not change
and it was not rotated, because its position did not change
therefore
it underwent
a reflection
343 divided by 7 is 49
There are 49 groups of 7 in 343
The answer is 49
Answer:
It's irrelevant.
Step-by-step explanation:
20 theater tickets cost 20T, 16 cinema tickets cost 16C.
Their sum is 20T+16C
You can factor a 4 out of this expression to get 4(5T+4C).
The two expressions are completely equivalent: there is no reason, in general, to prefer 20T+16C or 4(5T+4C).
Sometimes, the exercise may ask explicitly for the factored form.
In other cases, one of the two expression might be more useful: if you had to divide everything by 2, of course it's easier to write
If instead you had to subtract 10T, it would be more useful to write
To recap, 20T+16C and 4(5T+4C) are completely equivalent, and unless you have explicit requests, you may prefer one or the other depending on the calculations you have to do.
Step-by-step explanation:
Option D is the correct answer because 3.544 is greater than 3.455
The area would be 441 m².
We first find the length of the given rectangle. We know area is length times width, that the area is 405 and the width is 15; this gives us:
405 = 15L
Divide both sides by 15:
405/15 = 15L/15
27 = L
Calculate the perimeter of the rectangle:
P = 2L + 2w = 2(27) + 2(15) = 84 m
The side of the square is 1/4 the perimeter of the rectangle we just found:
1/4(84) = 21 m
The area of a square is equal to its side length squared:
A = s² = 21² = 441 m²
