Answer: 3/2
Step-by-step explanation:
Rise over run!!!
Subtract y values, divide that by the subtracted x values.
7-4/4-2= 3/2
I think the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.
but l also think it could be 12 percent error.
a) Both the length and the width of the rectangle are square roots of integers.
b) The length and the width of the rectangle are 6√5 units and 3√5 units, respectively.
<h3>How to analyze irrational numbers</h3>
Irrational numbers are numbers that not rational, that is, numbers that not of the form m / n, where m and n are integers and n is different of zero. Rational numbers may be integers or not.
Now, the statement indicates that the length and the width of rectangle have measures of 2 · x and x, respectively, and that the area of the rectangle is equal to 90 square units. The area formula is presented below:
90 = (2 · x) · x
90 = 2 · x²
x² = 45
x = √45
x = √(9 × 5)
x = √9 × √5
x = 3√5
a) Both the length and the width of the rectangle are square roots of integers.
b) The length and the width of the rectangle are 6√5 units (approx. 13.416 units) and 3√5 units (approx. 6.708 units), respectively.
