Answer:
B
Step-by-step explanation:
I think the answer is bbecause for perimeter you just add all the sides up. so you would add 8+8 or 8x2 which would be 16 and 3x2 or 3+3 which is 6. Then you add the two roducts you got together to find the final sum added together which would be 22.
Answer:
Step-by-step explanation:
a. The older one is, the higher their salary, with a couple of rare exceptions.
b. See attached figure
c. Salary of L60,000/year.
d. Age of 35 to earn L40,000/yr
Mathematically written:
3 * x + 7 = 25
3x + 7 = 25
3x = 25 - 7
3x = 18
x = 18 / 3
x = 6
Proof:
3 * 6 + 7 = 25
18 + 7 = 25
25 = 25 → both sides of the equation are equal, our answer is correct
Notes:
A number - Is an unknown number, called a variable, which in this case is substituted by the letter x.
