Answer:
C
a = 1 : b=-8; C = 12
Step-by-step explanation:
I think you did not include the sign between the x^2 and the 8x...my guess is that it is a minus.
By process of elimination the answer is not B or D bc the a-value is 1 not 0.
Then the +12 you did include in the original question indicates that the c-value is 12 not -12 eliminating answer A.
Answer:
a(14)=469762048
Step-by-step explanation:
geometric sequence= a(n)=a*r^(n-1)
we have:
a=7
r=28/7=4
So:
a(14)=7*4^(14-1)
=7*4^(13)
=469762048

You can converte them to a common denominator like 6. 1/2 would be 3/6. 2/3 would be 4/6.
Y = 12x - 5x - 2
first simplify the equation by subtracting like terms (in this case):
12x - 5x = 7x
y = 7x - 2
Since you are finding the x, you must isolate the x. Do the opposite of PEMDAS.(Note: because there is a equal sign, what you do to one side, you do to the other)
y = 7x - 2
y (+2) = 7x - 2 (+2)
y + 2 = 7x
(y + 2)/7 = 7x/7
x = (y + 2)/7
x = (y + 2)/7 is your answer

a²+b² = c² where a and b are legs and c is the hypotenuse
So...
a²+4²=13²
a²+16=169
a²=153
a=√153
answer: approx. 12.37 units
