Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term
a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8
an=8+6(n-1)
expand
an=8+6n-6
an=6n+2
3rd option
Answer:
31.5 square inches
Step-by-step explanation:
First, you need to enlarge each side with a scale factor of 1.5.
7 inches = 10.5 inches
2 inches = 3 inches
The new sides are 10.5 and 3 inches long. Now, you need to use these side lengths in the area formula of a rectangle.
A = Bh
A = 10.5(3)
A = 31.5 in.²
Answer:
x = 5, x=-2
Step-by-step explanation:
The factors are x-5 and x+2:
Set each factor equal to zero and then solve each of them for x to find out what values of x make the polynomial equal to zero.
x-5 = 0 , x+2 = 0
x=0+5 , x=0-2
x=5 , x= -2....
