Answer:
-3
Step-by-step explanation:
The product (the result of a multiplication) of 4 and a number. Let x be the unknown number:
4 · x = 4x
Plus 17:
4x + 17
Is 5:
4x + 17 = 5
Solve:
4x = 5 - 17
4x = -12
x = -12 ÷ 4
x = -3
An=a1+d(n-1)
a1=first term
d=common difference
n=which term
common difference is 5 first term is 2
an=5+2(n-1)
19th term is n=19
a19=5+2(19-1)
a19=5+2(18)
a19=5+36
a19=41
19th term is 41
Answer:
Angle b= angle c =83degree
Angle d =97degree
Step-by-step explanation:
Since isosceles:
Angle b =angle c
Angle a= angle d
Angle d =a=97
Sum of quadrilateral inner degrees:360
(360-2x97)/2=b=c=83
Step-by-step explanation:
at s = -3
at s = -2
at s = -1
at s = 0
at s = 1
at s = 2
at s = 3
First difference
Second difference
Third difference
18 -12 -2 0 0 4 18
-30 10 2 0 4 14
40 -8 -2 4 10
-48 6 6 6
180-95=85
subtract 5 divide by 2 which makes y 40
85+40=125
y=40
x=85
I hope this helps you
