Which shows a perfect square trinomial?
anastassius [24]
The answer is <span>c. 16x2 + 24xy + 9y2.

Since we need trinomial (three term expression) choices a and b are incorrect because they have only two terms.

So, our square trinomial is a</span>² + 2ab + b² or a² - 2ab + b²
a² + 2ab + b² = (a + b)²
a² - 2ab + b² = (a - b)²

Let's check choices c and d:
c) 16x² + 24xy + 9y²
a² = 16x²
a² = (4x)²
a = 4x

b² = 9y²
b² = (3y)²
b = 3y

a² + 2ab + b² = (4x)² + 2 * 4x * 3y + (3y)² = 16x² + 24xy + 9y²
CORRECT

d) 49x² - 70xy + 10y²
a² = 49x²
a² = (7x)²
a = 7x

b² = 10y²
b² = (y√10)²
b = y√10

a² + 2ab + b² = (7x)² + 2 * 7x * y√10 + (y√10)² = 49x² + 14xy√10 + 10y²
INCORRECT

So, c) is correct answer

Helppp meeee pleaseeeee!!!A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the s
Dvinal [7]

Answer:

Answer: No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

Let n equal the number, and let x equal the smaller number. Let's put this into equation form to make everything easier to understand.

x < n

n = 2x + 3

n = 2x + 1

Note how n equals two different things. In other words, how can n equal 2x + 3, but also equal 2x + 1? The equations have different y-intercepts but the same slope, meaning there are no solutions, or points where the lines would intercept. The only answer that highlights this is the third option.

To further clear things up, let's go through the other answers to make sure we're correct.

Answer 1: Two situations do not describe the exact same line; all parts of the question are unique.

Answer 2: The equations do not have different slopes, so this reasoning is invalid.

Answer 4: The situations describe two equations with the same slope but different y-intercept, not the other way around. In equation form, 2 = 2, but 3 ≠ 1.

Therefore, the only correct answer is option 3.

Given the linear function k(x) = 12 and m(x) = 3x - 5, find the new function j(x) = k(x) * m(x).
Step2247 [10]
J(x) = 12(3x - 5)
j(x) = 36x - 60
I am fairly certain that the new linear function is j(x) = 36x - 60
