Answer:
42.25 units²
Step-by-step explanation:
The perimeter of a square is P = 4s.
26 = 4s
26/4 = s
6.5 = s
The side length of the square is 6.5 units.
The area of a square is A = s²
6.5²
= 42.25
The area of the square is 42.25 units².
Answer:
x=8
Step-by-step explanation:
normally it would be 2x-1=
x+9 so now we have to combine the x into one fraction which will be 2x-1=
+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=
+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped
The answer is 1.5x10⁹ That is the scientific notation
