It’s 6 my bad if I’m wrong
You multiply 1.4x10= 14 and 7x10=70 then divide both by 14 and get 1/5 <span />
Answer:
D) 16x^2 + 4x
Step-by-step explanation:
So a since there is two lengths and two height, you are gonna have to add them all up.
<u>5x^2 + 2x</u> + <u>5x^2 + 2x</u> + <u>3x^2</u> + <u>3x^2</u>
<u>(</u>See why I put the length value and width value twice? Because there is two of each.)
Now start adding up common factors. Let's start with any x^2
10x^2+2x + 2x + 6x^2
I added up the 5x^2 together to get 10x^2 and I added the 3x^2 together to get 6x^2, now you are gonna add those two up
16x^2 + 2x + 2x
(Just from looking at this, you can easily cross out answers A and B)
Now add the x together
16x + 4x
So the the answer is D
Answer:
If the sign before the no. is same then they will get added and the resultant will have the same sign too.
Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.
So , -28-12 = -40
Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.
So,( -28)+38+(-12)
= -28+38-12
= -40+38
= -2
We know that 40> 38
sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign
I hope this helps you...
No matter what units you are exchanging to and from, the number of unit cubes will remain constant. For example: If I had a cube who's side was 10 km long, the number of unit cubes would be the volume of the cube which in this case is 1000 km³. So there would be 1000 unit cubes. Then, if I changed the side from 10 km to 10 in, and find the volume, it would be 1000 in³, meaning there are 1000 unit cubes! So the answer to your question is: The number of unit cubes remains constant
