To add/subtract fractions you need to have a common denominator...
(2/2)(4n/15)+(5/5)(n/6)
8n/30+5n/30
(8n+5n)/30
13n/30
base: b
height: b
A = 1/2 (b · b) = 1/2(b²) = b²/2
sum is six less than area
b + b = 6 - ↔b²/2
2b = b²/2 - 6
4b = b² - 12 <em>multiplied by 2 to clear the denominator</em>
0 = b² - 4b - 12
0 = (b - 6)(b + 2)
0 = b - 6 0 = b + 2
b = 6 b = -2 (Negative so disregard)
A = b²/2 = (6)²/2 = 36/2 = 18
Answer: 18 units²
Hi, it is very simples.
Look :
2a - 9 = -85
Pass the term -9 to the left side of equation, but changing the sinal
2a = -85 + 9
Sum -85 +9 = -76
Then,
2a = -76
Nos, pass the 2 dividing -76
a = -76 ÷ 2
a = - 38
