The complement is what adds to an angle to get 90 degrees

so

x is 25 mroe than 4 times y
x+y=90

x=25+4y
sub 25+4y for x

25+4y+y=90
25+5y=90
minus 25 both sides
5y=65
divide both sides by 5
y=13

sub back
x+y=80
x+13=90
x=77 degrees

Factor the expression.
g100num [7]

Answer:

(x + 1) (3 x^2 + 1)

Step-by-step explanation:

Factor the following:

3 x^3 + 3 x^2 + x + 1

Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):

3 x^2 (x + 1) + (x + 1)

Factor x + 1 from 3 x^2 (x + 1) + (x + 1):

Answer:  (x + 1) (3 x^2 + 1)
