Go to -5 on the number line, then move 3 spaces to the right

-5 + 3 = -2

Go from +3 on the number like and move to the left 5 times that would put you on the number -2.

So -5+3=-2

Answer:

add 7 to 9 times k : 7+9k

c cubed minus the product of 5 and q plus 4 : $c^{3} - 5q + 4$

twice r plus 7 is equal to 45 minus r : 2r+7=45-r

Product of h and 4 is subtracted from one-fifth of x is 35 :(h*4) - 1/5*x

one third of the difference bewteen 6 and p is added to 8 : (6-p)+8

Help!! - 2.10 - (4 points)

Answer:

Approach: Difference of Squares Pattern

$4 {x}^{2} - 25 = (2x - 5)(2x + 5)$

Step-by-step explanation:

The given binomial is:

$4 {x}^{2} - 25$

We can rewrite to obtain:

${(2x)}^{2} - {5}^{2}$

This is a difference of two squares, so we will factor using difference of squares pattern.

Recall that:

${a}^{2} - {b}^{2} = (a + b)(a - )$

If we let

$a = 2x$

and

$b = 5$

Then we can factor the given binomial to obtain:

${2x}^2 - {5}^{2} = (2x - 5)(2x + 5)$

$\therefore4 {x}^{2} - 25 = (2x - 5)(2x + 5)$

The number sentence 4x6=6x4 is an example of the what property

monitta

Answer:

commutative property of multiplication

Step-by-step explanation:

The value of the product of the given equation remain the same while the order is reversed

The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication

Reason:

The given number sentence is 4 × 6 = 6 × 4

Required: The property the number sentence is an example of (represent)

Solution:

The difference between the left and right expression is that the order of the

values being multiplied is changed or reversed (commute)

Therefore, the number sentence states that the value of the multiplication

of two variables remain equal when the places of variables are

interchanged as follows; a × b = b × a

a × b = b × a is an example of commutative property of multiplication

Therefore;

4 × 6 = 6 × 4 is an example of the commutative property of multiplication
