Step-by-step explanation:
Given that,
Length, l = (3d+2) m
Width, b = (d+5) m
(a) Perimeter of the rectangle,
P = 2(l+b)
P = 2(3d+2+d+5)
= 2(4d+7)
P = 8d+14
(b) If P = 30 cm.
8d+14 = 30
8d = 16
d = 2
(c) l = (3(2)+2) = 8 m
b = (2+5) = 7 m
The area of this rectangle,
A = lb
A = 8×7
A = 56 cm²
Hence, this is the required solution.
The complete equation is x^2 + 13x + 169/4 = 157/4
<h3>How to determine the number that completes the square?</h3>
The equation is given as:
x^2 + 13x = -3
Let the coefficient of x be represented with k.
So, we have:
k = 13
Divide both sides
k/2 = 13/2
Square both sides
(k/2)^2 = 169/4
Add 169/4 to both sides of the equation
x^2 + 13x + 169/4 = -3 + 169/4
Evaluate the sum
x^2 + 13x + 169/4 = 157/4
Hence, the complete equation is x^2 + 13x + 169/4 = 157/4

The linear function representing the above function is
F=0.4x+2
Step-by-step explanation:
Let the total monthly cost be represented as $ F
Let the number of songs downloaded in a month be x
Given: cost of downloading one song= $ 0.40
Monthly subscription fee (one time monthly) = $ 2
Hence total monthly cost-
Total monthly cost= cost of downloading “x” songs + monthly subscription fee
Total cost of downloading “x” songs monthly= number of songs downloaded* cost of downloading one song
Total cost of downloading “x” songs monthly=$ 0.4x
Hence Total monthly cost= 0.4x + 2
We have assumed total monthly cost as “F”
F=0.4x+2
