Answer:
a
n=1/2 an - 1
Step-by-step explanation:
64,32,16,8,4. is a geometric sequence. this is a sequence where, to get from one term to the next, there is a number that you have to multiply it by. this is the same for all parts of the sequence.
Angle ABD=87 degrees
angle ABC+angle CBD= angle ABD
Therefore, 9x-1+6x+58=87
15x+57=87
15x=87-57
15x=30
x=30/15
x=2
Angle ABC= 9x-1
=9(2)-1
=18-1
=17 degrees
Answer:8
Step-by-step explanation:
X+56=x^2
X^2-x-56=0
X^2-8x+7x-56=0
X(x-8)+7(x-8)=0
(X+7)(x-8)=0
X+7=0 or x-8=0
X=-7 or x=8
4(20+12)/(4-3) = 4(32)/1 = 128
Use order of operations (PEMDAS) Please Excuse My Dear Aunt Sally, and solve for parantheses, then multiply parentheses and then divide by 1.
