Check my Work: Factoring for 2y^+9y-18 is (2y-3) (y+6) true or false?

Alexxandr [17]

It is true because when you separate 2y^2 +9y -18, you are supposed to get the factors (2y-3)(y+6), when you multiply this it gives you the first equation, we know this because when we multiply the first term it gives us exactly 2y^2 and if we multiply the last ones it gives you -18, now here is the tricky part, when we multiply the middle part we get 12y and -3y, when we add these up we get 9y, now is that the same middle as in the equation? Yes… then our factors are correct making this true

Hope this helps

How many distinct diagonals of a convex heptagon (7-sided polygon) can be drawn?

valkas [14]

The convex heptagon has 14 distinct diagonals can be drawn

Step-by-step explanation:

A polygon is said to be a heptagon if it has 7 vertices, 7 sides and 7 angles. A heptagon is called a convex heptagon if the lines connecting any two non-adjacent vertices lie completely inside the heptagon

The formula of number of diagonals in any polygon is $d=\frac{n(n-3)}{2}$ , where

d is the number of the diagonals of the polygon
n is the number of sides of the polygon

∵ The heptagon has 7 sides

∴ n = 7

∵ The number of diagonals = $\frac{n(n-3)}{2}$

- Substitute n by 7 in the rule above

∴ The number of diagonals = $\frac{7(7-3)}{2}$

∴ The number of diagonals = $\frac{7(4)}{2}$

∴ The number of diagonals = $\frac{28}{2}$

∴ The number of diagonals = 14

The convex heptagon has 14 distinct diagonals can be drawn

How do i use the decimals 2.47,9.57,and 7.1 to write two different addition facts and two different subtraction facts?

VARVARA [1.3K]

Answers

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47

Explanation

A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts.

In this case we are going to write two different addition facts and two different subtraction facts as follows:

2.47,9.57,and 7.1

Addition facts

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

Subtraction

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47
