Answer:

wrong the answer is really D:10

Step-by-step explanation:

First, find the lengths of the legs of the right triangle.

horizontal leg = 4 - (-4) = 8

vertical leg = 3 - (-3) = 6

a2 + b2 = c2

82 + 62 = c2

64 + 36 = c2

100 = c2

100

= c

10 = c

Three boards are placed end to end to make a walkway. The first board is 4 feet inches 10 long, the second board is 2 feet 11 in

Strike441 [17]

Answer:

12 ft 2 in.

Step-by-step explanation:

Conversion: 1 ft = 12 in.

Add the lengths of the boards.

4 ft 10 in. + 2 ft 11 in. + 4 ft 5 in. =

= 4 ft + 2 ft + 4 ft + 10 in. + 11 in. + 5 in.

= 10 ft + 26 in.

= 10 ft + 24 in. + 2 in.

Since 1 ft = 12 in., then 24 in. = 2 ft.

= 10 ft + 2 ft + 2 in.

= 12 ft 2 in.

Which expression can be used to find the difference of the polynomials?

nadya68 [22]

Answer:

D is correct. ( 4m - 5 ) + ( -6m + 7 - 2n )

Step-by-step explanation:

We are given a difference of two polynomial

(4m-5) - (6m-7+2n)

We need to choose correct choice which is equivalent to given expression.

Here we have minus sign between two parentheses.

First we distribute minus sign over (6m-7+2n) using distributive property.

Minus sign will distribute with each term inside (6m-7+2n).

When it will distribute it changes the sign of each term inside the parentheses.

$6m\rightarrow -6m$

$-7\rightarrow +7$

$+2n\rightarrow -2n$

After distribution we get

( 4m - 5 ) + ( -6m + 7 - 2n )

Thus, D is correct option which is similar to given expression.
