Answer:

Step-by-step explanation:

if the base=x

length of one leg is =4x-6

length of the other leg is also =4x-6 (isosceles)

P=x+4x-6+4x-6=51

9x-12=51

9x=51+12

9x=63

x=63/9=7

x=7

Classify each polynomial by its degree and bt its number of terms (i.e. cubic or degree=3; trinomial. (a) 5x^4-8 (b) 4a^2-2a-16
lord [1]

Answer:

a. 4th degree binomial

b. 2nd degree trinomial

c. 3rd degree monomial.

Step-by-step explanation:

In order to find each of these, start by writing the degree based on the highest exponent. The work for a is done for you below.

5x^4 - 8

This means it is a 4th degree.

Now we can decide what the final word is based on how many terms there are. In this one there is 2, so we call it a binomial.

4th degree binomial.

HElP IM GIVING BRAINILYIST

Answer:

D.

Step-by-step explanation:

The difference in pizza delivered between driver A and driver B is 10 pizzas.

We can find this by doing 20-10 which is 10.

The MAD is 2.

D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.

Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.

Hope this answer helped! :)

Answer:

  (c)  y -2 = 6/5(x -1)

Step-by-step explanation:

The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)

_____

<em>Additional comment</em>

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

__

The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).
