Answer:
D) 
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation
<em> x² + 5 x + 8 = 4</em>
⇒ 
<u><em>Step(ii):</em></u>-
By using (a + b)² = a² + 2 a b + b²
⇒ 
⇒ 
⇒ 
⇒ 
⇒
<u><em>Final answer:-</em></u>
First year- 62,000
Second year- 7% increased in rent= 66,340
Third year- 7% increased in rent (66,340)= 70,984
Fourth year- 7% increased in rent (70,984)= 75,953
Fifth year- 7% increased in rent (75,953)= 81,270.
Total 5 years lease- 356,547.
She bought 11 shirts and 4 pants
Let x= pants
Let y= shirts
x+y=15
x+7=y
x=y-7
(y-7)+y=15
2y=22
y=11
x+y=15
11+x=15
x=4
Therefore, Elaine bought 11 shirts and 4 pants
Answer:
Step-by-step explanation:
Givens
You have the hypotenuse: 13
You seek the adjacent side: x
You have the angle enclosing the 2: 47 degrees.
The relationship is the Cosine
Solution
Cos(47) = opposite / hypotenuse
Cos(47) = 0.6820 From your calculator
Cos(47) = x / 13 Multiply both sides by 13
13*cos(47) = x
x=8.866
