Answer:
9) p = 48
10) a = 3.6
Step-by-step explanation:
9) p/8 + 3 = 9
p/8 = 6
p = 48
10) 12a/4 + 18/3 = 20.4
4a + 6 = 20.4
4a = 14.4
a = 3.6
a² + 10a + 16
Find two numbers whose product equals 16 and sum equals 10:
<u>Product = 16</u> <u>Sum = 10</u>
1 * 16 1 + 16 = 17 <em>doesn't work</em>
2 * 8 2 + 8 = 10 THIS WORKS!
4 * 4 4 + 4 = 8 <em>doesn't work</em>
Since 2 & 8 satisfy our requirements, those are the values that go into the parentheses.
Answer: (a + 2)(a + 8)
Note: when there is a coefficient for a², a different method is used to find the factors.
Since you are solving for x, you need to isolate x on one side of the equation. Start by subtracting C from both sides.
0 = x + a / b - C
Subtract x from both sides to have it on the left side of the equation.
-x = a / b - C
Make x a positive number by dividing both sides by negative one.
x = - a / b + C
