For this case we have to factorize the following trinomials as the product of two binomials.
We have then:
a2 + a - 20
(a + 5) (a-4)
a2 - 9a + 20
(a-5) (a-4)
a2 - 8a - 20
(a-10) (a + 2)
a2 - 12a + 20
(a-10) (a-2)
a2 - 19a - 20
(a-20) (a + 1)
Answer:
11
9.6
Step-by-step explanation:
absolute value makes the number positive.
Step-by-step explanation:
value of d = 90° ( as it's a perpendicular)
e = 49° ( vertically opposite angle)
as, sum of all angles on a straight line is 180°
so,
48° + f = 180°
f = 180 - 49 = 131°
f = 131°

Start with 8*2=16
116-8= 108
108(16)=1728
3^2+4=13 13(1728)=22464
4(22464)=89856
The answer is 89,856
