Answer: 13
Step-by-step explanation:
Add 3 to each side. That original 3 is cancelled out so you're left with 4x=11. Divide each side by 4 and that leaves you with x = 3.5
Now all you have to do is multiply 4 by 3.5 which is 14. You now have to subtract 1 and your answer is 13.
Answer:
37.5
Step-by-step explanation:the formula of surface area of a square is 6a²
and a is 2.5 in this case,so 6*2.5*2.5=37.5
Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
Answer:
C.
Step-by-step explanation:
3 times 2 is 6, 2 times 5 is 10, 5 times 3 is 15. However you need 2 for each since there are 3 sets of two equal faces. So it will be 6+6+10+10+15+15
