Find an expression for the perimeter of rectangle ABCD. Use the formula P= 2l + 2w.
natita [175]

Answer:

(b)

P = [4(4a + 3b]/(2a + b)

Step-by-step explanation:

P = 2L + 2W

P = [2(5a + 4b) + 2(3a + 2b)]/(2a + b)

P = [10a + 8b + 6a + 4b]/(2a + b)

P = [16a + 12b]/(2a + b)

P = [4(4a + 3b]/(2a + b)

Angle 1 and angle 2 are supplementary angles. m<1 is 4y + 7, and m<2 is Sy + 4. Find m<2.
Doss [256]

Step-by-step explanation:

First, we should define supplementary angles.

Supplementary angles are angles that add up to 180 degrees.

Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees

(

4

y

+

7

)

+

(

9

y

+

4

)

=

180

Now just solve for one variable

13

y

+

11

=

180

13

y

=

169

y

=

13

Now the question asks for m<2, which is

9

y

+

4

So we just plug in

9

⋅

13

+

4

=

121

So m<2 is 121

Does this table represent a function
Viktor [21]

Answer:

None repeating X on the table is a function, if it repeats than not a function.  

Step-by-step explanation:

I am not able to see the table but if X has repeating points then it is not a function. If it repeats the Y point then that is ok.
