Use foil (a + 3)(a - 2)

blsea [12.9K]

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 :

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

Y=2x and x+3y=-14 substitution to solve each system of equations

Sergeeva-Olga [200]

You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2

Substitute the value of x to the first equation.
y = 2(-2) = 4

What is the formula for the following arithmetic sequence?

vlabodo [156]

$a_{n}$ = 12 + (- 6)(n - 1 )

This is an arithmetic sequence with n th term

$a_{n}$ = $a_{1}$ + (n - 1)d

here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and $a_{1}$ = 12, hence

$a_{n}$ = 12 + (- 6)(n - 1)

use this formula to find the 30 th term

$a_{30}$ = 12 + (- 6 × 29) = 12 - 174 = - 162
