The answer is B. 15 is 3*5. Since there is a subtraction sign after it we can eliminate the first one. The best answer is the second one because when you put the two parenthesis together you get a negative and then a positive.

Use the process of elimination to find the answer.

Two positive factors will result in all positive trinomial values.

One negative factor and one positive factor will always result in a negative c value, which this trinomial doesn't have.

The answer is B. (3x - 2y)(5x - 2y).

ABCD is a parallelogram. What is the measure of ∠ACD?

Igoryamba

Step-by-step explanation:

Here

5x+16+7x-3+6x+5 = 180(being sum of triangle)

or, 18x=180-18

or, x= 162/18

so, x = 9

now,

here,

<ACD = <ACB(diagonals of parallelogram bisect eachother)

or, <ACD = 7x-3

or, <ACD = 7×9-3

or, <ACD = 63-3

So, <ACD = 60°

Finger [1]

Step-by-step explanation:

Let the number be x.

Half of a number is x/2 and a third of the number is x/3

ATQ,

$x+\dfrac{x}{2}+\dfrac{x}{3}=275\\\\\dfrac{6x+3x+2x}{6}=275\\\\\dfrac{11x}{6}=275\\\\x=\dfrac{275\times 6}{11}\\\\x=150$

Frist no is 150

Second no is 150/2 = 75

Third no is 50
