Hi!
In order to solve this equation you can either add 31 or 7 to both sides. Since you mentioned 7, we'll go with that. 2x - 7 + 7 = 14x - 31 + 7. Then simplify. 2x = 14x - 24. Then subtract 14x from both sides. -12x = -24. Divide both sides by -12 to get x = 2. Check your answer. 2 * 2 - 7 = 14 * 2 - 31. -3 = -3. So x = 2.

Answer:
234 ft²
Step-by-step explanation:
Area of parallelogram = base x height
in our case, base length = 26 feet and height = 9 feet
hence,
Area of parallelogram = 26 x 9 = 234 ft²
Answer:
$38,562.5
Step-by-step explanation
Using the compound interest formula
A = P(1+r/n)^nt
P is the principal = $125,000
r is the rate = 6% = 0.06
time t = 5years
n = 0.25 (quarterly payment)
Substitute
A = 125000(1+0.06/0.25)^5(0.25)
A = 125000(1+ 0.24)^1.25
A = 125000(1.24)^1.25
A = 125000(1.3085)
A = 163,562.5
Hence the interest earned = 163,562.5 - 125000
interest earned = $38,562.5
