You can figure this out if you just look at (x+a)^2 = x^2 + 2ax + a^2. See, the constant term, a^2, is the coefficient of x (2a), divided by 2 (2a/2=a), and then squared (a^2)
<span>So you equation has 8x. 8/2 = 4, and 4^2 = 16. So the answer is A.</span>
Answer: 3. Distributive
Step-by-step explanation:
Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.
For example: a (b+c)= a b+ac , where a,b,c can be any expression.
Given expression: -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.
Hence, the correct option is 3. Distributive.
The rest of properties cannot work for multiplication over addition as they are used for one operation.
Answer:
x=8
Step-by-step explanation:
The answer is the ratio of A's to the number of classes is 7 to 4. That's false. For the statement to be true the ratio should have been 4 to 7.
