Answer:
-36
Step-by-step explanation:
-(36/-6) to the power of 2 is -36.
The perimeter of the first figure is 34 cm and the area is 64 cm².
The perimeter of the second figure is 38 cm and the area is 60 cm².
The perimeter of the third figure is 30 cm and the area is 36 cm².
The perimeter of the fourth figure is 72 cm and the area is 200 cm².
The perimeter of the fifth figure is 30 cm and the area is 36 cm².
To find the perimeter of each, we add the area of all sides. For the first figure, the missing sides are 1 cm and 6 cm. To find the area, we have two rectangles whose dimensions are 6x10 and 1x4.
For the second figure, the missing sides are 4 cm and 3 cm. To find the area, we have two rectangles whose dimensions are 4x12 and 3x4.
For the third figure, the missing sides are 3 cm, 3 cm and 8 cm. To find the area, we have two rectangles whose dimensions are 4x3 and 3x8.
For the fourth figure, the missing sides are 10 cm, 10 cm, 6 cm and 6 cm. To find the area, we have two squares whose dimensions are 10x10.
For the fifth figure, the missing sides are 3 cm and 9 cm. To find the area, we have two rectangles whose dimensions are 3x6 and 6x3.
Answer:
8, 4, and 2 can not be the lengths of the sides of a triangle.
Step-by-step explanation:
If a and b are the two side's length of a triangle then the length of the third line (c) will be governed by the relation
(a+ b) > c > (a - b)
Now, the two sides length of a triangle are given by 8 and 4 then the length of the third side (x) will be given by
(8 + 4) > x > (8 - 4)
⇒ 12 > x > 4 ........... (1)
But here the third side length is 2 which does not satisfy the above condition (1).
Hence, a triangle can not have side lengths 8, 4, and 2. (Answer)
Answer:
A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y) .
Step-by-step explanation:
Plot an <u>open hole</u> at -6; shade to the <u>right</u>
The open hole is because we don't include -6 itself.
The shading to the right indicates all numbers larger than -6.
