Answer:
4b + 10c= T
Step-by-step explanation:
Since the variable x has an invisible one next to it, which is 1x, it is 6x.
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
Mistake in Line 2 : Was in the determining the values for a ,b,c
Mistake in Line 4 : Not taking the square roots of both sides.
Step-by-step explanation:
First Mistake : Line 2
Second Mistake : Line 4
Correct Solution :
Y = 3(3) +15
y = 9 + 15
y= 24
