I'm a little confused, it's about Combining like terms but I did don't understand​
ella [17]
2(-n-3)-7(5+2n)

First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.

2 times -n= -2n

2 times -3= -6

-7 times 5= -35

-7 times 2n= -14n

This leaves you with

-2n -6 -35 -14n

Next, combine like terms.

(-2n) + (-14n)= -16n
(-35) + (-6)= -41

This gives you

-16n-41, which is B in your answer choices.

Hope this makes sense!! :)

Margie has a $50.00 budget to purchase $45.00 pair of boots. If there is an 8% sales tax rate then how much under budget will Ma
LuckyWell [14K]
She will be $1.40 under budget.

8% = 8/100 = 0.08

Adding this to 100% of the price of the shoes, we get 108% = 108/100 = 1.08.

We multiply the price of the shoes by this:
45*1.08 = 48.60

Subtract this from 50:
50 - 48.60 = 1.40

Answer :Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

d(0,0)

i(5,5)

n(8,4)

g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

Two pairs of sides

Each pair having two equal-length sides which are adjacent

The angles being equal where the two pairs meet

Diagonals as shown in dashed lines cross at right angles,  and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.
