Answer:
(x − 5) (x + 4)
Step-by-step explanation:
x² − x − 20
Factor using AC method:
1 × -20 = -20
Factors of -20 that add up to -1: -5 and 4
Divide by 1 and reduce: -5/1 and 4/1
(x − 5) (x + 4)
Answer:
36 units
Step-by-step explanation:
there is 12 units at is base and 9 as its height
you have to use the Pythagorean theorem to find the hypotenuse
c= √(a^2+b^2)( be being 12 and a 9)
plug it in and get c=√(81+144)=√225=15
perimeter is a+b+c
now that we have c do 12+15+9
=36
