Formula: an = a1(r)^n-1
n = term number
a1 = first term
r = rate
Plug our values in:
n = 4
a1 = 15
r = 1/3
a4 = 15(1/3)^4-1
a4 = 15(1/3)^3
a4 = 15(1/27)
a4 = 0.5555555556
a4 = 0.6 to the nearest tenth
Answer: the bottom rectangle is 21 square units
The top triangles are each 6 square units
Step-by-step explanation:
Do 6 times 3.5 to find area of rectangle
Then do 3 times 4 divided by 2 for each of the top triangles
Answer:
2 and -10
Step-by-step explanation:
let the two integers be x and y.
so, x+y=-8---‐-------(1)
and,
x=y+12-------‐-----(2)
from (1) and (2),
(y+12)+y=-8
or, 2y=-8-12
or, y=-20/2
or, y=-10
substitutting the value of y in (2),
x=-10+12=2
therefore the required integers are 2 and -10.
