<h3>hello!</h3>
Use the distributive property:-
4(2x-1)
8x-4
8x-4+3=8x+1
8x-8x-4+3=1
8x-8x-1=1
0-1=1
-1=1
Wait, what? -1 is equal to 1?
Hence, the equation has no solutions.
Hope it helps :)
Answer:
Yes! You can
Step-by-step explanation:
1. If this is rows and columns it is doable, however if you are speaking columns by rows it isn't
2. You multiply them like normal except when you reach the end on your 2x2 matrix you repeat the cycle

Answer:
2x +11
Step-by-step explanation:
Answer:
$3952.13
Step-by-step explanation:
Annuity amount = future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
FV = Future value = $75,000
R = interest rate = 8%
N = number of years = 12
Annuity factor = [(1/08)^12 - 1 ] / 0.08 = 1.8977126
Annuity amount = $75,000 / 1.8977126 = $3952.13
Area = length x width
replace the known information into the equation:
area = 2/3
width = 1/2
so now the formula looks like:
2/3 = 1/2 x L
to solve for L we divide both sides by 1/2
L = 2/3 / 1/2 which = 2/3 * 2/1 = 4/3 = 1 and 1/3 km
