Answer:
option-A
option-D
Step-by-step explanation:
We are given a complex number as
we know that whenever we have
where
a is the real number
b is imaginary number
now, we can verify each statement
option-A:
we can see that
a=7
and
a is the real number
so, 7 will be real number
so, this is TRUE
option-B:
we know that
so, imaginary number is 
while it is mentioned square root 3 is the imaginary part of the number
so, this is FALSE
option-C:
We can see that coefficient of i is b
and
so, this is FALSE
option-D:
we know that
'a' and 'b' are sum of real and imaginary number
so, this is TRUE
Answer:
the value of x that makes this equation true is 9
Step-by-step explanation:
2(x - 6) + x + 14 = 4(x - 3) + 5
<em>open the parenthesis</em>
2x - 12 + x + 14 = 4x - 12 + 5
<em>add 12 to both sides of the equation</em>
2x - 12 + 12 + x + 14 = 4x - 12 + 12 + 5
2x + x + 14 = 4x + 5
<em>subtract 5 from both sides of the equation</em>
2x + x + 14 - 5 = 4x + 5 - 5
3x + 14 - 5 = 4x
3x + 9 = 4x
<em>subtract 3x from both sides of the equation</em>
3x - 3x + 9 = 4x - 3x
9 = 4x - 3x
9 = x
check the answer:
2(x - 6) + x + 14 = 4(x - 3) + 5
2(9 - 6) + 9 + 14 = 4(9 - 3) + 5
29 = 29
Answer:
Use the given <u>functions</u> to <u>set up</u> and simplify 7/l ⋅ (10<em>s</em> − 10/<em>r</em>) ⋅ (7(10s −10)).
7(10<em>s</em> −10) = 70<em>s</em> −70
7/l ⋅ (10<em>s</em> − 10/<em>r</em>) ⋅ (7(10<em>s</em> - 10)) = 4900(<em>sr</em>-1)(s−1)/<em>rl</em>

Answer:
3520
Step-by-step explanation:
Because 3 feet are equal to a yard and 1760 yards are in one mile
So.. just add 1760+1760 and thats the equivalent of 2 miles
