Answer:

d. p = 2*20 + 2*10

Step-by-step explanation:

You know to find the perimeter, just add side + side + side + side.

And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.

So add 20 + 20 + 10 + 10.

To simplify this, say 2*20 and 2*10. And then add them.

So it is D

Can anyone help me answer 4 and 5? Plzz

#4

Examine the relationship between y and x, waiting until later to examine the y-intercept.    For example:  If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table.  If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.

Also note that all y values in the table are positive, so a negative slope would be inappropriate.  That eliminates choices A and D.

Focus now on the remaining choices B and C.  Again, let x= 2 and determine the associated y value.  Which y value is closer to the table's 6.5?

B:  0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)

C:  3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)

C is the correct answer.

Answer:

B = j + H

Step-by-step explanation:

Given:

j = - H + B

Solve the equation for B

j = - H + B

Add H to both sides of the equation

j + H = - H + B + H

j + H = B

B = j + H
