Answer:

\left(a+3\right)\left(a-2\right)=a^2+a-6=

Step-by-step explanation:

Given expression is \left(a+3\right)\left(a-2\right).

Now we need to multiply this using FOIL.

F = First =\left(a\right)\left(a\right)= a^2

O = Outside =\left(a\right)\left(-2\right)= -2a

I = Inside =\left(3\right)\left(a\right)= 3a

L = Last =\left(3\right)\left(-2\right)= -6

Hence we get :

\left(a+3\right)\left(a-2\right)=a^2-2a+3a-6=a^2+a-6=

Answer:

(a+3)(a-2)=a^2+a-6

Step-by-step explanation:

The given expression is:

(a+3)(a-2)

Using FOIL, we multiply the;

First terms:a\times a=a^2

Outside terms: a\times -2=-2a

Inner terms:3\times a=3a

Last terms:3\times -2=-6

Putting all together we have:

(a+3)(a-2)=a^2-2a+3a-6

This simplifies to (a+3)(a-2)=a^2+a-6

Danny earns a monthly allowance of twenty dollars and extra seventy five cents every time he is nice to his mom. Avery earns a m
Lerok [7]

Answer:

Danny: y-=.75x+20

Avery: y=1.25x+18

Step-by-step explanation:

To write a system of equations, it usually equals y=mx+b. Since Danny and Avery both earn the set monthly allowance of 20 and 18 dollars respectively, those numbers go on the variable b since it's a set amount and they start off with that amount of money if they weren't nice to their mom at all.

Since we are trying to find the overall amount of money, let y=total money a child earns every month and x=how many times the child is nice to their mother.

The extra .75 cents Danny earns go under the variable m because it is dependent on how many times he is nice to his mom. Along with Avery.

Please help! It’s due tomorrow it also says to show my work
Pani-rosa [81]

Given:

The inequality is

x+19\leq 23

To find:

The value of x and then graph on the number line.

Solution:

We have,

x+19\leq 23

Subtracting 19 from both sides, we get

x+19-19\leq 23-19

x\leq 4

It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.

The surface area of the solid is about ____ inches squared
Dafna11 [192]

Answer:

Surface area of the whole figure=  320.28inch^2

Step-by-step explanation:

The surface area of the figure :

Surface area of the cylinder(excluding top)+Surface area of the cone(excluding bottom)

Radius of the cylinder=3 inch     and  Height of cylinder=13 inch

Surface area of the cylinder with one circular face

                                    =2\pi rh+\pi r^2

As,     \pi =\frac{22}{7}= 3.14

   =(2*3.14*3*13)+(3.14*3*3)\\\\=244.92+28.26\\\\=273.18inch^2

Surface area of the cone excluding  base:

                =\pi *r*l

l= slant height=5 inch       r= radius= 3 inch

Surface area of the cone =3.14*3*5

                                        =47.1inch^2

Total surface area of the whole figure=273.18+47.1

                                                           =  320.28inch^2
