Answer:
140
Step-by-step explanation:
4 * 4 =16
Right triangle is 10 because 5 *4=10
9 * 9 = 81
7*5=35
16 + 10 + 81 + 35= 142
142 rounded to the nearest ten is 140
Step-by-step explanation:
An = -2 * An-1
What this means is that you multiply -2 to the term to get the next term.
Since our 1st term (A1) is -2, we have:
A2 = -2 * A1 = -2 * (-2) = 4,
A3 = -2 * A2 = -2 * (4) = -8,
A4 = -2 * A3 = -2 * (-8) = 16,
A5 = -2 * A4 = -2 * (16) = -32,
A6 = -2 * A5 = -2 * (-32) = 64.
Hence our first 6 terms in the GP are
-2, 4, -8, 16, -32 and 64.
-30 = 6z
Plug in 6(-5) and you get -30
Answer is A
Answer:
7 1/8 or 7.125
Step-by-step explanation:
first subsitute z for 4
28/4 - 4/4 + 1 1/8
then do 28/4 - 4/4 which is 6,
add that to 1 1/8
and get 7 1/8
