A. -f(1)=1,f(2)=2,f(n)=2f(n-1)f(n-2);n>2
12 ft maybe? i dunno im sorry if this is wrong
Answer:
16-x*(-7)=-154
7x =-154-16
7x/7=-170/7
X=-24.29
Step-by-step explanation:
Let x represent "my number"
The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
X-3 is the expression that shows it
