The statements that correctly represent the scenario stated are:
B. because losing 8 pounds is represented as -8 and doing this for 3 months would be 3 groups of -8 or 3 x -8
D. because they showed the weight loss as a negative integer and then put those into groups of 4 each using the distributive property)
The error with the other 2 choices is that the negative number is not correctly representing which part of the problem is a decrease. The negative sign is placed on the number of groups of.
Answer:
16p + 6
Step-by-step explanation:
(12p + 9) + (4p - 3)
12p + 4p = 16p
9 + (-3) = 6
Answer: 16p + 6
Answer:
x^2−6x+9
Step-by-step explanation:
To write a polynomial in standard form, simplify and then arrange the terms in descending order.
ax^2 + bx + c
Rewrite (x - 3)^2 as (x -3) (x-3).
(x - 3) (x - 3)
expand (x - 3 ) (x - 3) using the FOIL method
Apply the Distributive property
x (x - 3) - 3 (x - 3)
again
x * x + x * -3 - 3 (x- 3)
and again
x * x + x * -3 - 3x - 3 * -3
then simplify and combine like terms
- Multiply x by x
x^2 + x * - 3 - 3x -3 * -3
- Move -3 to the left of x
x^2 - 3 * x - 3x - 3 * -3
Multiply -3 by -3
x^2 - 3x - 3x + 9
Subtract 3x by -3x
x^2 - 6x + 9
Hope that helps!

20+10=30
Answer:
Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. From this law it is easy to show that the result of first adding several numbers and then multiplying the sum by some number is the same as first multiplying each separately by the number and then adding the products.
Step-by-step explanation:
a(a+b)
in this question first a will multiply by a+b.
like this;
a(a+b)
= a(a)+ab
= a^2+ab
