No x does NOT equal 16. you would substitute x for 16 which gives you 16+12. That equals 28 not 30. The correct answer is x=18
Answer: 11x - xy - 6
Step-by-step explanation:
(5x+6xy-4)-(-6x+7xy+2)
5x + 6xy - 4 + 6x - 7xy -2
11x - xy - 6
Answer:
Rational
Step-by-step explanation:
Because it gives whole number which is 11
10^4 = 10,000
9 x 10,000 = 90,000
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
