Let's take any edge length l. The diagonal has length

. In our case it's
Answer:
1. 10x^2 -4
2. 2a^5 + 5b
Step-by-step explanation:
1. Simplify 4(x^2 -1) to 4x^2 -4
then add that to 6x^2
2. 4a^5 - 2a^5 = 2a^5 and
4b+b = 5b
Answer: 20 Dollars
Step-by-step explanation:
15 divided by 3 is 5. So, then multiply 4x5 and that equals 20
Answer:
D.2
Step-by-step explanation:
First, you need to divide 34 and 60 by A.4, when you divide that you see that 4 dose not go in to 34 evenly and go"s in to 60 evenly, so this is incorect.
Now we will divide 34 and 60 by B.3, when you divide, you see that 3 dose not go into 34 evenly and go"s in to 60 evenly, so this is also incorect.
Then we divide 34 and 60 by C.1, when we divide this one you find that 1 go"s in to 34 evenly and 60 evenly, so this is a posible answer.
finally we divide 34 and 60 by D.2, when we do this we find that 2 go"s in to 34 evenly and 60 evenly, so this is also a posible answer.
All though C. and D. both go in to 34 evenly and 60 evenly, we are looking for the GCF (Greatest Common Factor). So the biggest number of C.1 and D.2, is D.2
So the answer is D.2.
Hoped this helped, Have a grate day!
Answer:mark is 7. Mike is 4
Step-by-step explanation:x+y=11. Y=2x-10 thus substituting for y in equation1 we have x+2x-10=11. 3x-10=11. 3x=11+10. 3x=21. X=21/3. X=7. Mike =(2×7)-10=14-10=4
