Step-by-step explanation:
the perimeter (P) is the sum of the 4 sides
(a)
P = a + b + c + d
= x + 7 + 2x + 2 + 8x + x + 10 ← collect like terms
= 12x + 19
(b)
If x = 4 , then
P = 12x + 19 = 12(4) + 19 = 48 + 19 = 67
(c)
If x = 2 , then
P = 12x + 19 = 12(2) + 19 = 24 + 19 = 43
(d)
P = a + b + c + d
= x² + 4x + 8 + 2x² + x ← collect like terms
= 3x² + 5x + 8
Answer:
x=9
Step-by-step explanation:
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
Answer:
38
Step-by-step explanation:
you start by taking 10_3 24_17 then you will see difference is 7 then you will take 7+31=38
Answer:
<u>69 years</u> after 2005 which is in <u>2074</u> year the average price of a studio in this city will reach $1081.10.
Step-by-step explanation:
Given:
Average Price to rent a studio is denoted by 'p'.
It is been approximated by equation:

where t ⇒ number of years since 2005
Now given:
Average Price to rent a studio p = $1081.10
Substituting the value of p in above equation we get;

Solving the new equation to find the value of t we get;

Dividing both side by 24.1 we get;

Hence<u> 69 years</u> after 2005 which is in <u>2074</u> year the average price of a studio in this city will reach $1081.10.
