Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentiation:
A = x^2 + 9x - 36. This factors into A = (x + 12)(x - 3). We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.
Note that if x = 3 the area becomes zero. So: x must be greater than 3, so that the (x - 3) factor is positive.
Example: If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.
Answer:
The scale factor of triangle ABC to triangle RST is 1/3
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ----> the scale factor
To find the scale factor divide the length side of the image (reduced triangle) by the corresponding length side of the pre-image (original triangle)
substitute the values
simplify
The scale factor is less than 1
so
Is a reduction
Answer:
A
Step-by-step explanation:
There are 360 degrees in a circle. 36 is one tenth of 360. It will take 10 turns to reach 360 degrees, and open the can.
Answer:
The answer is B
Step-by-step explanation:
B is the only one with a quotient that is a multiple of 8
Answer:
21.5 km
Step-by-step explanation:
We have to find the distance between two boat
We are given that
AC=2.1 km
BC=3.5 km
We have to find BC
The angle between two boat =110 degrees
Using cosine law
BC=
BC=
BC=
BC=21.507 km
Hence, the distance between two boat is 21.5 km
