Answer:
Sometimes, but not always.
Step-by-step explanation:
A parallelogram is a quadrilateral with two pairs of parallel sides, but there are no requirements for its interior angles. A rectangle, on the other hand, <em>must</em> have four interior 90 degree angles. So a rectangle is always a parallelogram, but a parallelogram is not always a rectangle.
Answer:
15x-8
Step-by-step explanation:
9x-12+4x+4+10x
9x+4x+10x -12+4
15x-8
The first factor must be at least 1 and less than 10.
The second factor must be a power of 10.
Move the decimal point to the left until the number is between 1 and 10. Count how many places you move the decimal point.23.6 → 2.36
You moved the decimal point 1 place to the left. The power of 10 is 10 to the power of 1
23.6 = 2.36 × 10 to the power of 1
