Coefficient of 24x+32+4x+3
coldgirl [10]

Firstly, you can combine like terms, or terms that have the same variable and exponents.


24x and 4x both have the variable "x" so it can be combined to make 28x


A coefficient is basically just the number that's used to multiply the variable

In this case, the variable is "x" and the number that will be multiplied to x is 28.


<em>The coefficient is 28.</em>

Find the slope from the points given: <br> (18, -5), (18, 20)
Ivahew [28]

Answer:

UNDEFINED

Step-by-step explanation:

change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.

A net and the prism it will form when it is folded are shown below.
Mashcka [7]

Answer:

Option A)724 square centimeters

Step-by-step explanation:

we know that

The surface of the prism is equal to the area of its six rectangular faces

The surface area is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

L=12\ cm

W=11\ cm

H=10\ cm

<em>Find the area of the base B</em>

B=LW

B=(12)(11)=132\ cm^{2}

<em>Find the perimeter of the base P</em>

P=2(L+W)

P=2(12+11)=46\ cm

<em>Find the surface area SA</em>

SA=2(132)+(46)(10)=724\ cm^{2}
