Answer:
Part A. C=9
Part B. (w+3)² =139
Part C. w = 8.8 inch
Step-by-step explanation:
Given from the question length of the the picture = (2w+12) inches
Width of the picture = w inches
Area of the picture = 260 inch²
Part A. Area of the picture with the given dimensions= w×(2w+12)
Or w(2w+12) = 260
2w²+12w = 260
2(w²+6w) = 2×(130)
w²+6w = 130
Or w²+6w +9 = 130+9 ⇒ which is in the form of w²+6w+c = 130+c
Therefore for c = 9 we will get a perfect square trinomial.
Part B. As we have seen the equation in part A.
As required equation will be (w+3)²=139
Part C. Since (w+3)² = 139
Then by taking under root on both the sides of the equation
(w+3) =√139 = 11.8
(w+3)-3=11.8-3
w = 8.8 inch
Answer:
i believe 1 3/7 is the answer! have a great day
Step-by-step explanation:
Answer:
A. Standard form: 
B. General form: 
Step-by-step explanation:
We have been given that center of a circle is at point (8,9) and radius of our circle is 10 units. We are asked to write the equation of our circle.
A. Since we know that the equation of a circle in standard form is: 
, where,
(x,y) = Any point on circle,
(h,k) = Center of the circle,
r = Radius of the circle.
Upon substituting our given values in standard form of circle's equation we will get,
Therefore, the equation of our given circle in standard form will be .
B. Since we know that equation of a circle in general form is: 
, where, A, B and C are constants.
Upon expanding our standard form of equation we will get,
Therefore, the equation of our given circle in general form will be .
The length of time that Linda borrowed for is 18 months.
<h3>
How long did Linda borrow the money?</h3>
The interest paid is a function of the amount borrowed, interest rate and the duration of the loan.
Time = interest paid / (interest rate x amount borrowed)
$99 / (0.01 x 550) = 18 months
