Answer:
width is 8, length is 32
Step-by-step explanation:
* = multiply or times
Let the width be x, then the length would be 4x
Perimeter = 2*length+2*width
80 = 2*4x+2*x
80 = 8x+2x
80 = 10x
8 = x (width)
32 = 4x (length)
Using quadratic formula:
2(x^2-2x + 1) +4=16
2x^2-4x+6=16
2x^2-4+6-16=0 (then divide both sides by 2)
X^2 -2x- 5= 0
Then use quadratic formula
Answer is;
x = 1 + square root of 6
x = 1 - square root of 6
Answer:
x^7 / y^4
Step-by-step explanation:
Please enclose a negative exponent inside parentheses:
x^9y^(-4)/x^2
Rewrite this in the form
numerator
----------------------
denominator
x^9 *
We get: ------------ divided by x^2
y^4
x^7
Since x^9 / x^2 = x^7, our final answer is --------
y^4
Answer:
8
Step-by-step explanation:
8 plus 9 plus 10 equals 27. so 8 is the smallest.
