I assume that the "d2" was a typo as a problem such as this with 2 variables would require a <em>system of equations</em>.
I also assume that the ? is a typo and will replace it with 0, however you can repeat my steps with whatever it actually it.
I assume that the correct form is 2 + 3a + 6 + a = 0
2 + 3a + 6 + a = 0
Combine like terms
8 + 3a + a = 0
8 + 4a = 0
move 8 to other side
4a = -8
a= -8/4
a = -2*
plug this value of a into the original equation
2 + 3(-2) + 6 + (-2) = 0
The statement is true!
<em>* This probably isn't your answer! Repeat my steps with whatever the value of "?" is.</em>
To find the surface area of a rectangle, you must use the formula: SA=2B+PH
SA=2(96)+34*14
SA=192+476
SA=668 inches squared

Same, in Maryland it's 11:54 PM right now.
Answer:
49%
Step-by-step explanation:
First, find 55% of 9 pounds.
55% = 0.55
9 × 0.55 = 4.95
Next, find 40% of 6 pounds.
40% = 0.4
6 × 0.4 = 2.4
Add the two values together.
4.95 + 2.4 = 7.35
Find the percentage 7.35 is of the total weight (15 pounds).
7.35/15 = 0.49
0.49 = 49%
49% of the new mixture is peanuts.
