Answer:
B = 2
Step-by-step explanation:
Factor the left side
2x² - 12xy - 32y² ← factor out 2 from each term
= 2(x² - 6xy - 16y²)
Consider the factors of the coefficient of the y² term (- 16) which sum to give the coefficient of the xy- term (- 6)
The factors are - 8 and + 2, since
- 8 × 2 = - 16 and - 8 + 2 = - 6, thus
x² - 6xy - 16y² = (x - 8y)(x + 2y)
and
2x² - 12xy - 32y² = 2(x - 8y)(x + 2y) ← in factored form
Compare the factored form to the right side
Thus B = 2
Answer:
Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
Step-by-step explanation:
HOPE THIS HELPS!
Y< X^-X-6
1. Solve the x first by factor.
2. X equals to (x-3)(x+2). X=3 or -2.
3. Looking at the problem, we see two similar answers with 3 and -2.
4. The correct answer is D, y=0. Because 0 is less than 3, choice A fails because y is greater than x.
Answer:
8365431.2
Step-by-step explanation:
you will multiply 2987654 * the square root of 8 which is equal to at least 2.8 (that is rounding of course)=8365431.2
