Area = length X width
A = L(12 ft) x W(9 ft) but since the cost of carpet is given in square yards not square feet we need to convert
A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft) 1 yard = 3 feet so 1 foot = 1/3 yard
A = 4 yd x 3 yd divide by 3 ft which cancels the original ft and leaves yd's
A = 12 square yards
Cost = Area x price per yard
Cost = 12 sq yd X $35.00/ sq yd multiply and the sq yd's cancel leaving just cost in dollars
Cost = $420.00
The sum of the first 28 terms in the sequence is 5600
<h3>Sum of sequence</h3>
The sum of sequences are known as series. Given the following
a₁ = 92
a₁ = ai-1 - 8
For the second term
a2 = a1 - 8
a2 = 92 - 8
a2 = 84
Determine the sum of first 28th terms
S28 = 28/2[2(92)+(28-1)(8)]
S28 = 14(184+27(8))
S28 = 14(400)
S28 = 5600
Hence the sum of the first 28 terms in the sequence is 5600

Answer:
x = -4 and x = 5
Step-by-step explanation:
Since 
and 
both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.
Now we solve the equation.
