Answer:
There is 1 possible combination
Step-by-step explanation:
There are 5 assignments and they must be completed. 5. We want to find the number of combinations, then we use the formula of combinations.
Where n is the total number of objects and you choose r from them
Then
1. Simplify= xy^3
2. Factorise= (2x+1)(2x-1)
3.
4.
5. Estimate= 415.96
6. Highest Common Factor
70= -70,-35,-14,-10,-7,-5,-2,-1,1,2,5,7,10,14,35,70
98= -98,-49,-14,-7,-2,-1,1,2,7,14,49,98
7. Expand: 4-4x+x^2 Simplify: x^2-4x+4
8.
9. This is actually the easiest you take both the mass and volume and divide them :) which would be 500g<span>÷25cm^3=20g/cm3 </span>
10.
The ones I didn't answer I am not sure about and don't wanna give you any wrong answers :) Hope I helped though!
I believe the Surface Area is 37 inches^2 and the Volume is 15 inches^2
Answer:
To do this I am pretty sure your going to have to do some hard calculations.
<u><em>Lets go deeper</em></u>
<u><em></em></u>
so because it is a rectangle every angle is a right angle according to the property of a rectangle.
A right angle is 90 degress
So 8x+18=90
90-18=72
8x=72
72/8=9
x=9
