Length = 6x - 12
Width = x
Area of a rectangle:
A = length x width
3744 = (x)(6x - 12)
3744 = 6x^2 - 12x
6x^2 - 12x - 3744 = 0
Use the quadratic equation to solve for x. The two solutions end up being 26 and -24. Since length is a scalar measurement, it can only be positive. Thus, the value of x is equal to 26 inches.
Width = 26 inches
Length = 6(26) - 12 = 144 inches
Hope this helps!! :)
Answer: 32
Step-by-step explanation:
y = 17
and you are give the expression y + 15
so substitute the value of y into the expression and add them
17 + 15 = 32
Answer:
When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.

Answer:
L and W +5
Step-by-step explanation:
A1=15*12=180
A2=160+A1=340
340 factors
340,1,2,170,5,..., 20,17
20*17=340
|15-20|=5
|12-17|=5
add 5
