I don't know how to explain but it's right!
Answer:
1. A = 2x; P = 4x+2. A = 4; P = 10.
2. A = y² +2; P = 4y +2. A = 27; P = 22.
Step-by-step explanation:
1. The area is the sum of the marked areas of each of the tiles:
A = x + x
A = 2x
__
The perimeter is the sum of the outside edge dimensions of the tiles. Working clockwise from the upper left corner, the sum of exposed edge lengths is ...
P = 1 + (x-1) + x + 1 + (x+1) + x
P = 4x +2
__
When x=2, these values become ...
A = 2·2 = 4 . . . . square units
P = 4·2+2 = 10 . . . . units
_____
2. Again, the area is the sum of the marked areas:
A = y² + 1 + 1
A = y² +2
__
The edge dimension of the square y² tile is presumed to be y, so the perimeter (starting from upper left) is ...
P = y +(y-2) +1 +2 +(y+1) +y
P = 4y +2
__
When y=5, these values become ...
A = 5² +2 = 27 . . . . square units
P = 4·5 +2 = 22 . . . . units
1. 11 between x and 0 between y
2. 0 between x and 12 between y
3. 3 between x and 0 between y
4. 0 between x and 11 between y
5. 0 between x and 6 between y
6. (4,-2) and (-6,-2)
7. (2,12) and (2,-4)
8. (-7,-2) and (-7,-8)
9. (4,5) and (4,-7)
10. (9,9) and (-11,9)
11. (4,2) and (-10,2)
12. 4 units
13. 7 units
Hope this helps!
Answer:
11 units right
Step-by-step explanation:
11 units right
from A (-5, 1) to A' (6, 1)
(-5 + 11, 1 ) = (6, 1)
Tangent ratio is the ratio of opposite side to adjacent side of a right triangle. Same as the sine and cosine ratios, tangent ratios can be used to calculate the angles and sides of right angle triangles.
