Answer:
The length of the rectangle is 11 inch and its width is 8 inch.
Step-by-step explanation:
Given:
Rectangle 
and rectangle 
.
Let the width of the rectangle be 'x' inch.
Its length = '(x+3)' inch
Area of the rectangle = 
⇒
= 
Now for rectangle its width is decreased by 1 inch and length is doubled,the area 
will increased by 66 sq-inch.
So,
According to the question.
⇒ Area of rectangle with width '(x-1)' and length '2(x+3)'='(2x+6)' .
⇒ 
Plugging the values of 
in terms of .
⇒ 
Plugging = into the equation.
⇒ 
⇒ 
⇒ 
⇒ 
Now using quadratic formula we can find the value of 'x'.
Quadratic formula, (x)= 
x= -9 and x= 8
Discarding the negative value.
Our width = 'x' = 8 inches.
So the length of the rectangle = 11 inches and width of the rectangle = 8 inches.
The answer to this question is x^(rt + s) since (x^r)^t becomes x^(rt) by the exponent power of a power property. Then multiplying powers of the same base results in the exponents being summed.
Answer: The length of BD is 2.4
Step-by-step explanation: BD is a leg of a right triangle, so use the
Pythagorean Theorem a² + b² = c²
BC is the hypotenuse here, so that is c = 3
We can use the segment CD as side b = 1.8
We will call BD side a, and solve to find that length.
a² + (1.8)² = 3² Square the known values of b and c
a² + 3.24 = 9 Subtract 3.24 from both sides.
a² = 9 - 3.24 Simplify
a² = 5.76 Find the square root of both sides (Calculator time!)
a = 2.4
