40min*1.05=42min they spent 42 min together
ps: check the multiplication it's 01:30 and I did that in head
Use the ! tool to find the # of combinations.
8!/5! = 40,320/120 = 336
Answer:
Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.
Step-by-step explanation:
It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.
We have to find the expression which represents the perimeter, in centimeters, of the triangle.
Perimeter of a triangle = Sum of its all the sides.

On combining like terms, we get



Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.

Step-by-step explanation:
For question 9 - It is stating that AE is equal to 38. So the length of the entire line is 38. We then need to look at which figures are actually useful to us, which in this case is AC which is 10. Therefore the answer is as simple as 38-10, which gives us an answer of 28 for the other half of the line, notated as CE.
