Answer:

1.2

Step-by-step explanation:

1) factor this equation:

36*5=180

so what*what=180

and what+what=-36

-30*-6=180

and

-30-6=-36

substitute -30x and -6x in place of -36x

5x^2-30x-6x+36

split in two groups:

group a) 5x^2-30x

(gcf of 5x)

5x(x-6)

group b) -6x+36

-6(x-6)

(5x-6)(x-6)=0

5x-6=6/5 or 1.2

x-6=6

Find the 4th term if the sequend in which a1 = 2 and a n+1 = -4a n + 2

pshichka [43]

$a_n_+_1=-4a_n_+_2$

dividing both sides by -4, we get:

$a_n_+_2=- \frac{a_n_+_1}{4}$

this means, each term is its previous term divided by -4.

now we can construct the sequence as follows:

$a_1=2$

$a_2=- \frac{a_1}{4}= - \frac{2}{4}= -\frac{1}{2}$

$a_3=- \frac{a_2}{4} =- \frac{ \frac{1}{2} }{4}=- \frac{1}{8}$

$a_4=- \frac{a_3}{4}=- \frac{ \frac{1}{8} }{4}=- \frac{1}{32}$

Answer: the last term is -1/32

Solve the equation<br> 2(x+4)=-5x+1

ivanzaharov [21]

Expand

add 5x to both sides

simplify 2x + 8 + 5x to 7x + 8

subtract 8 from both sides

simplify 1 - 8 to -7

divide both sides by 7

Answer: x = -1.

If 90 is 80 percent of the value what is the value

OLga [1]

If 90 is 80% of the whole value, then 1/4 of 90 added to 90 will be the value, because 1/4 of 80% (which is 20%) added to 80% will give us 100%

So,
90/4=12.5
90 + 12.5=102.5

At least, that's my take on it

Answer:

x=3

Step-by-step explanation:

If all of the angles and sides are congruent, then you would just subtract 7 by 4 and get 3 for x.
