Please help me I’m so lost !!!!
Tasya [4]

Answer:

4095

Step-by-step explanation:

\sum _{n=1}^63\left(4^{n-1}\right)\:

\sum _{n=1}^63\cdot \:4^{n-1}

Compute general progression:

\frac{3\cdot \:4^{\left(n+1\right)-1}}{3\cdot \:4^{n-1}}=4

r=4\\

a_1=3\cdot \:4^{1-1}

a_1=3

nth term is computed by:

r=4,\:a_n=3\cdot \:4^{n-1}

plug in the values n=6,\:\spacea_1=3,\:\spacer=4:

=3\cdot \frac{1-4^6}{1-4}

=4095

How do work this out
BabaBlast [244]
We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35. 

Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.

So split the 2r into these two terms and group.

(5r^2 - 5r) + (7r - 7)

Factor both groups.

5r(r-1) + 7(r-1)

The factors of (r-1) can be added together to get the answer.

(r-1)(5r+7)

Factor completely. 12x4+18x3+45x2 Enter your answer in the box.
lukranit [14]

QUESTION 1

The given expression is

12x^4+18x^3+45x^2

The greatest common factor is 3x^2.

We factor to obtain;

3x^2(4x^2+6x+15)

QUESTION 2

The given quadratic equation is

x^2+6x-72=0

We split the middle term to obtain

x^2+12x-6x-72=0

Factor by grouping;

x(x+12)-6(x+12)=0

(x+12)(x-6)=0

Use zero product property;

(x+12)=0\:\:or\:\:(x-6)=0

x=-12\:\:or\:\:x=6

QUESTION 3

The given system of equation is

3x+4y=-8

7x-3y=6

If we multiply 3x+4y=-8 by 3, we obtain;

9x+12y=-24

If we multiply 7x-3y=6 by 4 we obtain;

28x-12y=24

Adding the last two equations will give us;

37x=0

The y-variable is eliminated.

Answer:Multiply 3x+4y=−8

by 3. Multiply 7x−3y=6 by 4. Add the resulting equations together.

Math 7a using number sense to solve equations
Anika [276]
Simple...

you have: \frac{n}{3} =12


and

\frac{n}{3} =-12

To solve for....\frac{n}{3} =12

Multiply to remove the denominator-->>

3*  \frac{n}{3} =12*3

n=12*3

n=36

Then-->>>

\frac{n}{3} =-12

Do the same thing-->>

3* \frac{n}{3} =-12*3

n=-12*3

n=-36

Thus, your answer.
